The release notes state that "Building GDB and GDBserver now requires a
C++17 compiler (for instance, GCC 9 or later)". Looks like we already
satisfy this requirement with GDB_DEP_NO_STD_FUTURE.
gdbserver now has a dependency on iconv.h, for uclibc configurations we
need to make sure this is satisfied.

Add newly released mold version 2.32.0 from upstream
https://github.com/rui314/mold
New features
- mold supports a feature called Identical Code Folding, or ICF. As the
name suggests, ICF finds identical functions and merges them to reduce
the size of an output file. This is especially effective for
template-heavy C++ programs since templates tend to be instantiated to
the same machine code for different types. For example,
std::vector<int> is likely to be instantiated to the same code as
std::vector<unsigned>. We've made an improvement to our ICF algorithm
so that the --icf feature is ~50% faster than the previous version.
(fa8e95a)
- The -z rodynamic option is now supported for compatibility with LLVM
lld. With the option, mold places the .dynamic section into a
read-only segment. (9a233df)
Bug fixes and compatibility improvements
- Previously, mold behaved differently compared to other linkers if both
-z defs and --undefined=ignore-in-object-files were given (#1270).
Now, they override each other so that the mold's behavior is
compatible with others. (8cd85aa)
- Previously, --dependency-file mistakenly recorded response files as
dependencies (#1258). This bug has been fixed. (4281f45)
- There was a bug that mold corrupted debug info section contents when
the --relocatable option was given (#1265). This issue has been fixed.
(08b0a16)
- [PPC64] The R_PPC64_TPREL16_LO_DS relocation type is supported.
(a8cd2e8)
- [ARM64, PPC64, LoongArch] mold 2.31.0 or earlier may have failed with
an assertion failure when creating a large output file (#1224). This
issue has been resolved. (c7c8583)

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.
Successfully tested the following canadian builds:
x86_64-unknown-linux-gnu,pru
x86_64-w64-mingw32,pru
