help
|
|
If you're specifying an addition target architecture,
|
|
you'll probably need to also provide options to make
|
|
the compiler use this alternate arch.
|
|
|
|
For example, if you're building a compiler that can build
|
|
both powerpc and powerpc64 binaries, you'll need to
|
|
specify -m64 here.
