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.
