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. |
