19 allows you to specify an additional target arch.

33 help
34 If you're specifying an addition target architecture,
35 you'll probably need to also provide options to make
36 the compiler use this alternate arch.
37
38 For example, if you're building a compiler that can build
39 both powerpc and powerpc64 binaries, you'll need to
40 specify -m64 here.

97 If your target CPU does not have a Floating Point Unit (FPU) or a
98 kernel FPU emulator, but you still wish to support floating point
99 functions, then everything will need to be compiled with soft floating
100 point support (-msoft-float).
