gnu: gcc: Fix compilation of libstdc++ for GCC 7 to 13.
With the introduction of GCC 14 as the default compiler, compilation of
libstdc++ of all previous versions would fail due to a different
signature for ‘__cxa_call_terminate’ (a builtin in GCC 14). This fixes it.
* gnu/packages/patches/gcc-libstdc++-newer-gcc.patch: New file.
* gnu/local.mk (dist_patch_DATA): Add it.
* gnu/packages/gcc.scm (gcc-7, gcc-8, gcc-9, gcc-10)
(gcc-11, gcc-12, gcc-13): Use it.
