- Fix building assembler files.
  https://github.com/llvm/llvm-project/issues/59978

- It checks for -nostdlib++ on the C++ compiler (g++) but then tries to
  pass it to the C compiler (gcc). This does not work:
  gcc: error: unrecognized command-line option '-nostdlib++'
  So use the C++ compiler for linking.
