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

33 If your target CPU does support the MIPS16 instruction set
34 and you want to use it for packages, enable this option.
35 MIPS16 produces smaller binaries thus reducing pressure on
36 caches and TLB.

183 If you're specifying an addition target architecture,
184 you'll probably need to also provide options to make
185 the compiler use this alternate arch.

187 For example, if you're building a compiler that can build
188 both powerpc and powerpc64 binaries, you'll need to
189 specify -m64 here.
