 104           Some builds may require a 'biarch' toolchain. This option

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