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

 119                   If you're specifying an addition target architecture,
 120                   you'll probably need to also provide options to make
 121                   the compiler use this alternate arch.
 122
 123                   For example, if you're building a compiler that can build
 124                   both powerpc and powerpc64 binaries, you'll need to
 125                   specify -m64 here.
