Allows building the #mold linker, which can then be used in the
cross-toolchain by passing the -fuse-ld=mold to the gcc flags. It is
much faster than ld or gold.
This requires a C++20 compiler and cmake.
Initially implemented by Arnaud, and HC added configure check for cmake.
Outstanding task to validate compiler is C++20 compatible.

Both D and GNAT have their own runtimes (resp. libphotos and libada).
It is still possible to build the compiler proper without any runtime,
and have an external runtime installed later. This is most commonly
found in embedded systems.
An example for D is: https://github.com/KitsunebiGames/tinyd-rt
An example for Ada: https://github.com/Fabien-Chouteau/bare_runtime

Musl was marked experimental in commit 08d91d41 ("musl: config is broken
for !EXPERIMENTAL"). Most of the reasoning for that change no longer
applies and as it's been about 8 years it's time to let musl loose on
the world. Drop the `depends on EXPERIMENTAL` and update the sample
configs for aarch64 and x86_64.
For powerpc64 the ABI needs to be elfv2. Enforce this via the powerpc
config. Add a sample configuration for powerpc-unknown-linux-musl.

macos-latest has recently (as of April 2024) started transitioning to
macos-14 (previously it was macos-12). This seems to be missing things
we rely on (e.g. makeinfo) and even when those are added throws other
errors. For now lets pin things to macos-12 until someone can spend
some time looking at why we can't use macos-14.

In canadian builds, the target toolchain running on the build
machine is not compiling and installing target Newlib. Thus it
cannot by itself link target executables. This results in
errors for gnuprumcu package when its configure script attempts
to test the compiler:
.../ld: cannot find crt0.o: No such file or directory
configure:3738: error: C compiler cannot create executables
Fix by passing the host toolchains's sysroot in target CFLAGS.
While at it, also add a missing passing of target LDFLAGS.

x86_64-unknown-linux-gnu,pru
x86_64-w64-mingw32,pru

This reverts commit 57f5909285. This was
originally added so that a toolchain could be built on a newer system but
run on an older one. With the benefit of hindsight that is probably the
wrong approach. The best way of achieving that goal would be to use
docker/podman container to provide an environment that is the same as
the oldest supported system and build inside that. The resulting
toolchain should be compatible with the old system and the new one.

This patch removes any dependency to the Oracle UEK Linux sources since
it can be easily replaced by a standard kernel explicitly pointing to

Starting from GDB 11.x, gmp is needed as a dependency to build full gdb.
And by default build system of native GDB will try to link with libgmp
of the build host. And to make sure that doesn't happen we need to
specify location of the target's sysroot so that library search starts
from there. Which we do in that change.
