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.
