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

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