Use 32-bit instructions only since currenlty there is no demand for a
larger address space. Provide one multilib with FPU and AltiVec support
and one without.
This patch should be applied to GCC 4.9 and mainline. I do not have
write access, so in case this gets approved, please commit it for me.
v2: Move MULTILIB_OPTIONS += m32 to right position in the file.
