  19           Some builds may require a 'biarch' toolchain. This option
  20           allows you to specify an additional target arch.

  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.
