Previously, gen-bootlin-toolchains did not add a `depends` guard to
limit the available toolchains based on the minimum required GCC version
for the user selected CPU tuning.
Now, the proper BR2_ARCH_NEEDS_GCC_AT_LEAST_X guard will be added based
on the version of GCC provided by the toolchain.

Previously, it was possible to select an external toolchain that did not
support the GCC arch tuning the user had selected. This is problematic
because it can lead to confusing error messages during builds [0].
Now, external toolchain selections will be filtered to only those that
support the required GCC version specified by the target arch tuning.
Note: this patch does not touch the Bootlin toolchain config file as it
is generated by a script.
Additional note: there is "soft" support for toolchains prior to GCC 4.8
but there are no accompanying BR2_ARCH_NEEDS_GCC_AT_LEAST_X symbols.
Instead of adding those, just use BR2_ARCH_NEEDS_GCC_AT_LEAST_4_8 which
is the minimum GCC version with claimed support [1].

released. Besides the usual updates of GCC, binutils, GDB, kernel
headers, and C libraries, support for AArch64 BE with musl has been

test cases.
All test cases where successfully tested:

Previously, it was possible for external toolchains to be used that had
support for languages or libraries that Buildroot was not aware of.
If Buildroot is not made aware of this support, it will not know to copy
the requisite libraries into the filesystem.
This is problematic as packages may perform their own checks [0] to find
out what the toolchain supports and builds will link against libraries
from the toolchain but will be missing dependencies in the filesystem.
Now, the support helpers alert the user when a toolchain supports a
language or library that has not been set in the Buildroot configuration.
Also, while we're here, add `-ffree-form` to the Fortran check to
suppress a meaningless warning.

Since the commit [1], the utils/genrandconfig script improved the
configuration randomization used by autobuilders. Since then it can
generate a configuration that is not suitable for an external toolchain
such the "Codescape IMG GNU Linux Toolchain".
Indeed this toolchain can be selected for mips32r5 or mips64r5 while only
mips32r2 or mips64r2 are really supported. The toolchain issue will be
fixed in a followup change.
We want to catch such issue in check_unusable_toolchain function otherwise
it is detected late during the sysroot import into staging and trigger
a weird error message:
ln: failed to create symbolic link 'output/host/mips64el-buildroot-linux-gnu/sysroot//nvmedata/autobuild/instance-25/buildroot/libc.a': No such file or directory
ln: failed to create symbolic link 'output/host/mips64el-buildroot-linux-gnu/sysroot/usr//nvmedata/autobuild/instance-25/buildroot/libc.a': No such file or directory
This is similar test than for the main sysroot check but this time we have
to use the toolchain cflags to check the architecture sysroot.
If the architecture sysroot doesn't exist, the toolchain will reply with
"libc.a".
Either the toolchain is really broken or we used a wrong target
architecture variant. In the later case, the toolchain infrastructure will
print a meaningful error message.
Note: We also may get a similar issue using the toolchain-external-custom package
if a toolchain is used with a wrong target architecture variant.

This commit modifies the toolchain-wrapper to make sure that the
CCACHE_COMPILERCHECK and CCACHE_BASEDIR are only set if ccache support
is enabled. Indeed, when BR2_USE_CCACHE is not set (or to a value
different than 1), we don't call the compiler with ccache, so there is
no reason to set those ccache environment variables, and they could
potentially conflict with a separate usage of ccache, outside of
Buildroot, for example when using the Buildroot SDK.
In particular, the value of CCACHE_BASEDIR doesn't not make any sense
when the Buildroot toolchain is not used during the Buildroot build,
as it points to the output directory $(BASE_DIR).
We pay attention to also not show those variables as being set in the
BR2_DEBUG_WRAPPER dump.
To help a little bit with this, a ccache_enabled boolean is introduced
to indicate when ccache is being used.
There is still quite a bit of #ifdef-ery involved, but it's not easy
to find a simpler way to organize the code.

YES and _VERSION and _SOURCE are set to empty before relaying the call

When we introduced support for the paranoid check of unsafe libraries
and headers path with commit 4ac8f78d37 (Add option for paranoid
unsafe path checking) back in 2014, we made it optional, as we expected
that would break quite a few packages.
Now, almost 8 years later, we only have three packages that explicitly
reference the option (dillo, gnuradio, and libtalloc), either in a patch
or in their .mk.
The option has been enabled by default since 2016, with 61c8854cef
(toolchain: enable paranoid unsafe path check by default), and that has
not triggered many build failures in a while.
The minimal defconfig used by test-pkg has also had it enabled as of
b6c98b3549 (minimal.config: add BR2_COMPILER_PARANOID_UNSAFE_PATH=y)
in 2017.
It is time to make that globally unconditional now.
There is still a remnant, in our binutils patches. As our toolchain may
get used outside of Buildroot, people may got the expectation that path
poisoning is only a warning, so we keep the current behaviour.

Since glibc 2.33 (upstream commit
7a55dd3fb6d2c307a002a16776be84310b9c8989), headers >= 5.4.0 are needed
to build glibc for RISC-V 32-bit. Indeed
sysdeps/unix/sysv/linux/riscv/configure.ac contains:
if test $libc_cv_riscv_int_abi = ilp32; then
arch_minimum_kernel=5.4.0
fi
In order to take into account this dependency, we add the appropriate
logic in package/glibc/Config.in and
toolchain/toolchain-buildroot/Config.in.
This change means that if headers < 5.4.0 are selected, then no C
library at all will be available for RISC-V 32-bit, as glibc is the
only C library supporting RISC-V 32-bit currently. However, thanks to
the recent addition of BR2_TOOLCHAIN_BUILDROOT_NONE, the
choice...endchoice for the C library selection will not be empty,
allowing the user to see the Config.in comment explaining why glibc
can't be selected.
Therefore, technically this commit does prevent from creating a
configuration with RISC-V 32-bit and headers < 5.4.0, but it will have
BR2_TOOLCHAIN_BUILDROOT_NONE=y, which is catched by
package/Makefile.in, which aborts the build early on pointing out that
the configuration is invalid.

In the internal toolchain backend, we have a choice..endchoice block
to allow the user to select the C library, between glibc, uClibc and
musl.
However, there are situations were no C library at all is
supported. In this case, the choice does not appear, and does not
allow to see the Config.in comments that are within the
choice..endchoice block and that may explain why no C library is
available.
For example, on RISC-V 32-bit, the only C library supported is glibc,
and the minimum kernel header version required by glibc on this
architecture is 5.4.0. In a future commit, we are going to add this
dependency on glibc (to fix build issues on configurations that have
headers < 5.4.0). But since glibc is the only supported C library on
RISC-V 32-bit, it means that the choice..endchoice for the C library
contains no entry, preventing from seeing the Config.in comment.
To address this issue, this commit adds a "dummy"
BR2_TOOLCHAIN_BUILDROOT_NONE option that shows up in the
choice..endchoice only when no C library is available. Thanks to this,
the choice..endchoice is never empty, and the Config.in comments can
be seen.
If the user keeps BR2_TOOLCHAIN_BUILDROOT_NONE selected, then the
build will anyway abort early because package/Makefile.in has a check
to verify that a C library is selected, and aborts the build if not.
Some could say that the problem should be resolved by instead
preventing the selection of headers < 5.4.0 on RISC-V 32-bit, but that
is difficult to do as the user can choose a custom header version, or
simply specific that (s)he wants to use the headers of the kernel
being built. In those situations, it's difficult to prevent selecting
headers < 5.4.0.
Prevent random configurations from triggering a build failure in our
autobuilders, by excluding that symbol from accepted configuration.

Startig with glibc 2.34, the gconv modules description has been split in
two:
- a common definition in the old location, /usr/lib/gconv/gconv-modules
- specific definitions in a subdirectory, /usr/lib/gconv/gconv-modules.d/
This is done so as to simplify the handling of glibc gconv modules, and
eventually to segregate those outside of glibc, and so that third-parties
may also provide their own gconv converters and their definitions.
And starting with that same glibc version, most of the gconv modules
definitions are moved to an extra configuration file in that
sub-directory.
It is thus no longer possible to use special code pages, like cp850,
which are very useful to access FAT-formatted devices.
Add support for this new gconv layout, while keeping support for older
glibc versions. Note that the modules themselves are not moved or
renamed, just the definition files have changed.
Instead of passing the one old gonv modules definitions file on stdin,
we pass the base directory to that file, and move into the script the
responsibility to find all the gconv definition files.
