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.
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.
