It'll probably take a little bit in the way of modification to the
netbsd OS aspect of the mips port. See gcc/config/mips/linux64.h as an
example. Most of that will be for abi support like you'd see on irix
(o32/n32/n64) at the same time. It'd probably be less work if you only
wanted a single abi - but then again, as most of the work has already
been done... :)
