This failed on our mips R5K platform as well.  A while I worked
on getting this to work on our oldish snap of NetBSD.  I will look
back and see what the changes were.  Some of them have been put
back I believe, but maybe not all of them.

I will send the patch directly to you to try.

I also did more mips2 instructions for fp.S and we build most
stuff -mips2.  The latest was the sqrt emulation for denorms,
which I believe is not in -current.
