103 Some builds may require a 'biarch' toolchain. This option

121 If you're specifying an addition target architecture,
122 you'll probably need to also provide options to make
123 the compiler use this alternate arch.
125 For example, if you're building a compiler that can build
126 both powerpc and powerpc64 binaries, you'll need to
