I've been attempting to build a cross-development tree with binutils
2.9.1 and egcs-1.1b, Greg Lehey gave me a poke about this. I didn't
realize the sparc64 code was in such bad shape. Ugh, what a mess!
I think I've got it building now; I'll keep track of what I had to
symlink, copy, and change if it actually works.

Do it anyhow. It only takes a few minutes, and you can then share
what you have with everyone else through pserver.

Looking at the NetBSD code would be helpful on this. There is no good
reason to differ from them; this will help our future NetBSD/OpenBSD
portability.
SPARC registers are really different from the Intel world. ;^)
