[Peter: drop 5.4.x bump]
Signed-off-by: Peter Korsgaard <peter@korsgaard.com>
While the kernel is built for the target, the build may need various host
libraries depending on config (and kernel version), so use HOST_MAKE_ENV
instead of TARGET_MAKE_ENV.
In particular, this ensures that our host-pkgconf will look for host
libraries and not target ones.
Fixes building scripts/dtc for Buildroot configurations enabling libyaml and
host-pkgconf for kernels after commit 067c650c45 (dtc: Use pkg-config to
locate libyaml).
With this enabled, we can drop the PKG_CONFIG_* variables for the
_NEEDS_HOST_LIBELF conditional, as those are included in HOST_MAKE_ENV.

When 'make' includes a new Makefile, it appends its path to the MAKEFILE_LIST
variable. From that variable, we construct a few set of derivative
variables:
pkgdir = $(dir $(lastword $(MAKEFILE_LIST)))
pkgname = $(lastword $(subst /, ,$(pkgdir)))
Essentially, pkgdir is the full directory where the package is located
(either relative to Buildroot's top directory for in-tree packages, or
absolute for packages in br2-external trees), while pkgname is the last
component of that directory.
pkgdir is in turn used to seed FOO_PKGDIR.
This all happens when we eventually call the package-generic infra,
later down in the file.
When they are parsed, the Makefiles for each linux-extensions are
appended to MAKEFILE_LIST, after the linux.mk one. But since they are
located in the same directory as the main linux.mk, the last component
of MAKEFILE_LIST, which is no longer the main linux.mk, will still yield
the correct values for the linux package.
This is a tough assumption we made there and then.
When we added the support for br2-external linux extensions, we where
very cautious to explicitly scan them from a directory named 'linux', so
that this would yield the correct package name.
And that worked well so far, until someone needed to build an older
kernel, for which our conditional patch is needed, and which just
failed:
/bin/bash: [...]/buildroot-external-linux-test/linux//0001-timeconst.pl-Eliminate-Perl-warning.patch.conditional: No such file or directory
When we scan linux extensions from a br2-external tree, the last
component of MAKEFILE_LIST is no longer in the same directory as the
main linux.mk, and thus the assumption above falls to pieces...
Again, when we added support for linux extensions from br2-external,
although we cared about the package name (pkgname), we completely missed
out on the package directory, and the LINUX_PKGDIR variable.
We do not have a very clean way out of this mess, but we have a nice
dirty trick: Scan the linux extensions from a br2-external tree before we
scan the in-tree ones. That way, the last component of MAKEFILE_LIST is
back to one that is in the same directory as the main linux.mk, and
we're back on tracks.
This is still very fragile, though, but short of a complete overhaul on
how packages are parsed and evaluated, this is the best we can come in
short order.

Currently the BR2_LINUX_KERNEL_DTB_IS_SELF_BUILT option is only
available to be selected by another config option. This option controls
if the Linux build system should build the DTB itself, or if buildroot
explicitly calls the Linux Makefile like "make something.dtb".
My use case: I want to build an OpenRISC image with a custom device tree
file. OpenRISC does not support appended DTBs, and I'm not using a
bootloader, but link everything into a single kernel (vmlinux) image.
The kernel option CONFIG_OPENRISC_BUILTIN_DTB allows me to specify a dtb
file, which is typically located in the kernel source tree in
arch/openrisc/boot/dts/NAME.dts.
Since my dts file is not part of the upstream kernel, I have two
options: either patch the kernel to include the DTS file, and then
specify it using the CONFIG_OPENRISC_BUILTIN_DTB option.
Or use buildroot's BR2_LINUX_KERNEL_CUSTOM_DTS_PATH config option to
copy any DTS file to the kernel source tree, and then specify this file
with CONFIG_OPENRISC_BUILTIN_DTB as before.
However, the second option also requries the buildroot option
BR2_LINUX_KERNEL_DTB_IS_SELF_BUILT to be set, otherwise I end up with a
"make -C kerneldir NAME.dts" call, which doesn't work (no such target
exists).
Currently the BR2_LINUX_KERNEL_DTB_IS_SELF_BUILT option exists, but it's
not visible/available. Simply making it available solves the problem for
me nicely.

>From patch [1] included in kernel >= 5.0:
"The upcoming GCC 9 release extends the -Wmissing-attributes warnings
(enabled by -Wall) to C and aliases: it warns when particular function
attributes are missing in the aliases but not in their target.
In particular, it triggers for all the init/cleanup_module
aliases in the kernel (defined by the module_init/exit macros),
ending up being very noisy.
These aliases point to the __init/__exit functions of a module,
which are defined as __cold (among other attributes). However,
the aliases themselves do not have the __cold attribute.
Since the compiler behaves differently when compiling a __cold
function as well as when compiling paths leading to calls
to __cold functions, the warning is trying to point out
the possibly-forgotten attribute in the alias."
Werror is set by default while building ppc kernel [2], but
some warning can be introduced while building current kernel with
newer compiler (for example building kernel 4.19 with gcc 9.1).
For the same reason why we remove Werror in packages's compiler
flags. Building with Werror is not bulletproof when we start
using a newer compiler that introduce new warnings.
This is the case here.
Also this option is a bit strange since it's specific to ppc kernels:
"The intention is to make it harder for people to inadvertantly
introduce warnings in the arch/powerpc code."
Other kernel developers on other arch may be interested by a
similar/more generic option.
So, It's clearly intended for kernel developers.
Instead of backporting this patch [1] to kernel 4.19, select
unconditionally the Kconfig option CONFIG_PPC_DISABLE_WERROR
that allow to disable Werror.
