I've had a quick look at this and I think it's caused by the way the ABI feature bits are tied to the processor. With a mipsel-* triple we end up with half-O32 half-N64 output but it should do the right thing with a mips64el-* triple.

I think we can leave this as a separate change since MIPS64 processors on a mipsel-* triple is known to be buggy at the moment.

Ok, I'll add that to this patch.
