add patch to fix multiarch support for RISC-V to all GCCcore 12.x and 13.x easyconfigs

[bedroge]

This fixes an issue where building GCC on RISC-V will fail due to:

/usr/include/stdio.h:27:10: fatal error: bits/libc-header-start.h: No such file or directory
   27 | #include <bits/libc-header-start.h>
      |          ^~~~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.

See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=106271 and https://bugs.gentoo.org/890636.

Also depends on easybuilders/easybuild-easyblocks#3256.

@bedroge Can you try again on RISC-V using an updated config.guess (see easybuilders/easybuild-easyblocks#3013)?

I gave it a try, but unfortunately that didn't help. I'm still seeing this error in gcc-12.3.0/stage2_stuff/gmp/config.log:

configure:5926: checking compiler gcc -O2 -pedantic
Test compile:

@bedroge Could it be related to static linking? See riscv-collab/riscv-gnu-toolchain#970

Not sure. It's gcc itself (built in stage1) that's failing to find libgcc_s.so, even when compiling some very basic code without static linking. This doesn't find it either (it does in that issue you referred to):

/path/to/build/dir/GCC_stage1_eb/bin/gcc --print-file-name=libgcc_s.so
libgcc_s.so

This library is in the stage 1 installation (in the lib dir), and I can work around it by setting $LIBRARY_PATH to the same value as $LD_LIBRARY_PATH here:
https://github.com/easybuilders/easybuild-easyblocks/blob/develop/easybuild/easyblocks/g/gcc.py#L617
Not sure why that's required here, and apparently not for other architectures.

By setting $LIBRARY_PATH the installation did complete, but the sanity check failed with similar errors:

Both libstdc++.so and libgcc_s.so are in %(installdir)s/lib, though, so setting $LIBRARY_PATH in the module file will probably solve that again.
Regarding nvptx, I guess that should be disabled on RISC-V?
