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