124 help
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.
