Masahiro Yamada a9847d1483 Makefile: delete HOSTFC and FC_FOR_BUILD
This definition of HOSTFC is completely wrong.

"$(HOSTLD)" should be "$(HOSTFC)".  Also, "echo" always succeeds, so
"which g77 || type -p g77 || echo gfortran" is never run.

Anyway, HOSTFC is most likely set to "/use/bin/ld" and nobody has
complained about it before me, so I guess it is not used at all.

At least grepping HOSTFC, FC_FOR_BUILD did not hit any packages.
Drop HOSTFC and FC_FOR_BUILD.

Yann E. MORIN e91dfc68d7 br2-external: make it available to post-{build, image} scripts
Currently, BR2_EXTERNAL is not always exported to sub-processes that we
spawn, like post-build or post-image scripts. This all depends on how
the user passes BR2_EXTERNAL; consider the following:

  - make BR2_EXTERNAL=/path/to/br2-ext
  - BR2_EXTERNAL=/path/to/br2-ext make

In the first case, it is just a make variable, not an environment
variable, and thus not exported, while in the second case it is an
environment variable and gets exported to all sub-processes make may
spawn.

Explicitly export it using EXTRA_ENV.

Thomas Petazzoni 158001f57b Turn the static lib option into a choice with more options
This commit turns the single static option into a choice, which offers
various possibilities:

 1. Build and use static libraries only;
 2. Build both shared and static libraries, but use shared libraries;
 3. Build and use shared libraries only.

On most platforms, (2) is currently the default, and kept as the
default in this commit. Of course, on certain platforms (Blackfin,
m68k), only option (1) will be available.

In addition to the introduction of the Config.in options, this commit
also:

 * Removes the 'select BR2_STATIC_LIBS' from 'BR2_BINFMT_FLAT', since
   with the use of a choice, we are guaranteed that BR2_STATIC_LIBS
   will be selected when the binary format is BR2_BINFMT_FLAT, since
   BR2_STATIC_LIBS will be the only possible solution in the choice.

 * Changes package/Makefile.in to use the proper
   --{enable,disable}-{shared,static} options for autotools packages.

[Thomas: remove useless empty newline right after 'choice'. Noticed by
Yann E. Morin.]

Thomas Petazzoni 665e13c85e Rename BR2_PREFER_STATIC_LIB to BR2_STATIC_LIBS
Since a while, the semantic of BR2_PREFER_STATIC_LIB has been changed
from "prefer static libraries when possible" to "use only static
libraries". The former semantic didn't make much sense, since the user
had absolutely no control/idea of which package would use static
libraries, and which packages would not. Therefore, for quite some
time, we have been starting to enforce that BR2_PREFER_STATIC_LIB
should really build everything with static libraries.

As a consequence, this patch renames BR2_PREFER_STATIC_LIB to
BR2_STATIC_LIBS, and adjust the Config.in option accordingly.

This also helps preparing the addition of other options to select
shared, shared+static or just static.

Note that we have verified that this commit can be reproduced by
simply doing a global rename of BR2_PREFER_STATIC_LIB to
BR2_STATIC_LIBS plus adding BR2_PREFER_STATIC_LIB to Config.in.legacy.

Thomas Petazzoni 4ac8f78d37 Add option for paranoid unsafe path checking
This commit adds a Config.in option to the "Build options" submenu to
enable paranoid checking of unsafe paths. This mechanism is added as
an option so that when we'll enable it in the autobuilders, people
trying to reproduce the build failures will be able to do so by just
downloading the configuration file. If instead we were leaving this
feature as an environment variable, everyone would have to remember to
pass this environment variable to reproduce build issues. And certain
build issues triggered by paranoid unsafe patch checking may not be
visible in the build output, for example when they happen during the
execution of configure scripts.

Since this option is fairly advanced, a new submenu inside "Build
options" is created, for Advanced options.

Yann E. MORIN 514d7cab61 infra: do not append an empty LD_LIBRARY_PATH
When we set LD_LIBRARY_PATH when building our host tools, we append any
pre-existing value to our custom path:
        LD_LIBRARY_PATH="$(HOST_DIR)/usr/lib:$(LD_LIBRARY_PATH)"

But then if LD_LIBRARY_PATH was previously empty, we end up with an
LD_LIBRARY_PATH that ends with a colon.

Also, when we check that an existing LD_LIBRARY_PATH does not contain
CWD, we previously did not look for a zero-length prefix.

Since 'man ld.so' says of LD_LIBRARY_PATH:
    A colon-separated list of directories in which to search for ELF
    libraries at execution-time. Similar to the PATH environment
    variable.

And POSIX states about PATH:
    A zero-length prefix is a legacy feature that indicates the current
    working directory.

And bash also recognises a zero-length prefix to search in CWD:
    A zero-length (null) directory name in the value of PATH indicates
    the current directory.

We may thus end up on a system where a zero-length prefix in
LD_LIBRARY_PATH is interpreted as CWD.

Do not append the previous LD_LIBRARY_PATH if it was empty, and check
for a zero-length prefix when checking dependencies.

Francois Perrad 2081534cd4 intltool: fix build issues
This commit fixes various build failures caused by the host-perl
series.

Currently, the variables PERL and PERL5LIB are available only during
the configure step of host-intltool, but they are also needed when
running host-intltool, in all packages that depend on
host-intltool. Without them, host-intltool cannot work as it doesn't
find the libxml-parser-perl module installed in
$(HOST_DIR)/usr/lib/perl.

This commit therefore makes the PERL and PERL5LIB variables global, so
that all packages can access them.

Thomas De Schampheleire 3ed0eada71 Makefile: unconditionally include pkg-utils.mk
Currently, pkg-utils.mk (included via package/Makefile.in) is only included
when a configuration file already exists. This means that none of the
utilities it defines are available without .config.

In particular:
- the MESSAGE macro, causing pretty build output. Since some make targets
  can be run even without .config, like 'make manual', not having this
  pretty printing is odd.

- pkgname, pkgdir: in a subsequent patch, these functions will be used for
  the generation of the manual, and since this should work also without
  .config, we need these functions to be available.

This patch moves the include of pkg-utils.mk from package/Makefile.in to
Makefile, outside of the check for .config.

This is a quick fix. The full solution involves to minimize the amount of
Makefile code that is guarded by a check on .config. This approach will be
taken in the 2014.11 release cycle.

Thomas De Schampheleire abb8a8dae4 infra: introduce a kconfig-package infrastructure
There are several packages that have a configuration file managed by
kconfig: uclibc, busybox, linux and barebox. All these packages need some
make targets to handle the kconfig specificities: creating a configuration
(menuconfig, ...) and saving it back (update-config, ...)

These targets should be the same for each of these packages, but
unfortunately they are not. Especially with respect to saving back the
configuration to the original config file, there are many differences.

A previous set of patches fixed these targets for the uclibc package.
This patch extracts these targets into a common kconfig-package
infrastructure, with the goals of:
- aligning the behavior of all kconfig-based packages
- removing code duplication

In order to use this infrastructure, a package should at a minimum specify
FOO_KCONFIG_FILE and eval the kconfig-package macro. The supported
configuration editors can be set with FOO_KCONFIG_EDITORS and defaults to
menuconfig only.
Additionally, a package can specify FOO_KCONFIG_OPT for extra options to
pass to the invocation of the kconfig editors, and FOO_KCONFIG_FIXUP_CMDS
for a list of shell commands used to fixup the .config file after a
configuration has been created/edited.

GCC has several builtin functions that implement atomic operations. Those
functions are architecture specific and may not be implemented by the
specific toolchain. In case of GCC for ARC those functions rely on
LLOCK/SCOND instructions which are optional in ARC CPU's. If ARC CPU doesn't
support those instructions but software tries to use them, then application
will be aborted with Illegal instruction exception. To avoid confusion user
should first specify that their CPU supports atomic extension, which will
allow selection of packages that use builtin atomic functions.

Francois Perrad f99a66de95 host-perl: export and rename PERL5LIB
The official Perl documentation refers only to PERL5LIB.
PERLLIB is obsolete, we don't need to be compatible with Perl4.

PERL5LIB is used in all environment, so it is simpler to just export it.

Fabio Porcedda 4b3bc153ad package/Makefile.in: don't force jobs when BR2_JLEVEL is empty
When the "BR2_JLEVEL" variable is empty use "make" without
the "-j" option, because to be able to use top-level parallel
make we must not force the number of jobs in sub-make.

Example:
	make BR2_JLEVEL= -j8

Thomas Petazzoni c5866be0ad toolchain: refactor Stack Smashing Protection support
This commit refactors how Stack Smashing Protection support is handled
in Buildroot:

 *) It turns the BR2_TOOLCHAIN_BUILDROOT_USE_SSP option into an option
    that only enables the SSP support in uClibc, when using the internal
    toolchain backend.

 *) It adds an hidden BR2_TOOLCHAIN_HAS_SSP option that gets enabled
    when the toolchain has SSP support. Here we have the usual dance:
    glibc/eglibc in internal/external backend always select this
    option, in the case of uClibc/internal, it gets selected when
    BR2_TOOLCHAIN_BUILDROOT_USE_SSP is enabled, in the case of
    uClibc/external, there is a new configuration option that the user
    must select (or not) depending on whether the toolchain has SSP
    support.

 *) It adds a new options BR2_ENABLE_SSP in the "Build options" menu,
    to enable the usage of SSP support, by adding
    -fstack-protector-all to the CFLAGS.

Gustavo Zacarias 71701eb6d7 nommu/flat: build packages with the correct FLAGS
When building for nommu flat targets the CFLAGS/CXXFLAGS/LDFLAGS must be
adjusted accordingly.
For gcc this means passing along -Wl,-elf2flt to signal the linker.
For ld this means -elf2flt.

Also correct the error in STACKSIZE settings from commit 9edf482d which
is setting gcc flags as ld flags and will surely fail (no package uses
it at the moment so it was never seen).

Thomas Petazzoni 796621c56a package/Makefile.in: fix ABI name for EABIhf targets
The current code to set ABI on ARM does the following:

ifeq ($(BR2_arm)$(BR2_armeb),y)
... set ABI without 'hf' suffix ...
else ifeq ($(BR2_ARM_EABIHF),y)
... set ABI with 'hf' suffix ...
endif

But since $(BR2_arm)$(BR2_armeb) will always be 'y' in the cases where
BR2_ARM_EABIHF is 'y', it means that the 'else' part of the condition
will never be used.

Fix this by appending 'hf' to the ABI variable when BR2_ARM_EABIHF is
selected.

[Peter: put EABIhf handling under arm/armeb conditional for consistency]
