mips.py: add mips32 softfloat targets

softfloat targets are for producing a userland (ie glibc, gcc) that
handles software floating-point emulation in userspace. The alternative
is configuring your kernel to emulate floating-point math, which is
slower but allows you to use a standard "hard float" userland.
