113        help
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.
