Ok, it is in fact doing the correct thing.

I'm really surprised we never hit this before in all of these years
:-) I guess we've simply never hit this kind of expression in a module
before.

The issue is that modules aren't a "final link", it's really more like
an intermediate partial link.

So we do end up seeing the R_SPARC_LO10 + R_SPARC_13 sequences in the
final module object.

Therefore, we really should handle R_SPARC_13 in the sparc module loader.

Richard, I want you to get full credit for this since you did all of
the dirty work :-) Would you please cons up a formal patch with commit
message and signoff for this and I'll push it around?

Thanks a lot!
