I see the same failures on aarch64-none-elf cross builds which use newlib:
/build-agent/temp/buildTmp/gcc-2/aarch64-none-elf/libstdc++-v3/include/aarch64-none-elf/bits/ctype_base.h:44:35:
error: '_U' was not declared in this scope
44 | static const mask upper = _U;
| ^~
/build-agent/temp/buildTmp/gcc-2/aarch64-none-elf/libstdc++-v3/include/aarch64-none-elf/bits/ctype_base.h:45:35:
error: '_L' was not declared in this scope
45 | static const mask lower = _L;
| ^~
/build-agent/temp/buildTmp/gcc-2/aarch64-none-elf/libstdc++-v3/include/aarch64-none-elf/bits/ctype_base.h:46:35:
error: '_U' was not declared in this scope
46 | static const mask alpha = _U | _L;
and so on.
