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].

"Toolchain prefix" option apparently doesn't have any help describing
it, which causes confusion when using external toolchain. Leaving this
option at default prefix name ("$(ARCH)-linux") when external toolchain
components are called with different prefix (e.g.
"$(ARCH)-unknown-linux-gnu") may cause build failure unless the prefix
symlink is already in place (e.g. when using Buildroot-generated

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.

Currently, glibc depends on !BR2_STATIC_LIBS in all the toolchain
variants.
However, for some architectures, glibc is the only supported libc. In
commit 3b3105328e ("Config.in: only
allow BR2_STATIC_LIBS on supported libc/arch"), we implemented a fix
to avoid configurations were BR2_STATIC_LIBS=y with an architecture
already supported by glibc, because these configurations are
impossible. This commit 3b3105328e
prevents from selecting BR2_STATIC_LIBS=y when the C library used for
the internal toolchain backend is glibc.
However, it introduces a discrepency between how this topic is handled
for internal and external toolchains:
- For internal toolchains, we prevent BR2_STATIC_LIBS=y if glibc is
chosen.
- For external toolchains, we allow BR2_STATIC_LIBS=y in all cases,
and it's each glibc toolchain that has !BR2_STATIC_LIBS
This commit addresses this discrepency by preventing BR2_STATIC_LIBS=y
if glibc is chosen in all cases.
Thanks to this, we can remove the !BR2_STATIC_LIBS dependency on both
the glibc package, and all glibc external toolchains.

Some external toolchains do not have gdbserver available, but the
option BR2_TOOLCHAIN_EXTERNAL_GDB_SERVER_COPY is always visible. And
when enabled, this option aborts with an error when gdbserver cannot
be found:
Could not find gdbserver in external toolchain
Due to that, some random configurations fail to build when
BR2_TOOLCHAIN_EXTERNAL_GDB_SERVER_COPY=y, for example with the Bootlin
toolchains for Microblaze or OpenRISC (because there's no GDB support
for those architectures).
One solution could be to make "Could not find gdbserver in external
toolchain" a warning instead of a hard error, but then nobody would
notice about this issue, in cases where it should legitimately abort
with a hard error.
So, the clean solution would be to add a
BR2_TOOLCHAIN_EXTERNAL_HAS_GDBSERVER. But that means all existing
external toolchains would have to be modified to select this option.
Instead, and as an exception, we chose to use inverted logic, and
create an option that is the opposite:
BR2_TOOLCHAIN_EXTERNAL_HAS_NO_GDBSERVER. By default, we assume
external toolchains have gdbserver. If
BR2_TOOLCHAIN_EXTERNAL_HAS_NO_GDBSERVER is enabled, we disallow the
BR2_TOOLCHAIN_EXTERNAL_GDB_SERVER_COPY option.
Note that the case of custom external toolchain does not matter: by
definition they are not tested by the autobuilders, and by definition,
we cannot know in menuconfig if the custom toolchain has or does not
have gdbserver. We could make a user-visible option for it, but that
adds no value over simply erroring out because the gdbserver binary
can't be found.
Similarly, we could add
default y if BR2_PACKAGE_GDB_ARCH_SUPPORTS
but that would make it impossible for someone to include a custom
gdbserver in their external toolchain, and gives no benefit at all.
This will help fixing:

Convert BR2_TOOLCHAIN_EXTERNAL_PATH to an absolute path when used.
Otherwise the symbolic links to the external toolchain binaries are
not installed in host/bin when BR2_TOOLCHAIN_EXTERNAL_PATH is relative.
This happens because TOOLCHAIN_EXTERNAL_INSTALL_WRAPPER
changes directory into host/bin to create the symbolic links.
From there the tools are no longer found via the relative path and
a single symbolic link host/bin/$(prefix)-* is created instead.
Although relative paths sounds like something less than ideal to put in
a Buildroot configuration, it's actually rather typical to put the
buildroot sources as a submodule (or subdirectory) of custom sources
(either in a BR2_EXTERNAL or not), in which case the relative path is
well-defined.
