104 Some builds may require a 'biarch' toolchain. This option
105 allows you to specify an additional target arch.

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