help
If your target CPU does not have a Floating Point Unit (FPU) or a
kernel FPU emulator, but you still wish to support floating point
functions, then everything will need to be compiled with soft floating
point support (-msoft-float).
Most people will answer N.
config USE_MIPS16

depends on HAS_MIPS16

help
If your target CPU does support the MIPS16 instruction set
and you want to use it for packages, enable this option.
MIPS16 produces smaller binaries thus reducing pressure on
caches and TLB.
Most people will answer N.

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.
