  37                   If you're specifying an addition target architecture,
  38                   you'll probably need to also provide options to make
  39                   the compiler use this alternate arch.
  40
  41                   For example, if you're building a compiler that can build
  42                   both powerpc and powerpc64 binaries, you'll need to
  43                   specify -m64 here.
