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

 114                   If you're specifying an addition target architecture,
 115                   you'll probably need to also provide options to make
 116                   the compiler use this alternate arch.
 117
 118                   For example, if you're building a compiler that can build
 119                   both powerpc and powerpc64 binaries, you'll need to
 120                   specify -m64 here.
