The patch that I think fixed this on mainline

This is a compiler bug rather than a linker bug.
The compiler must only apply %lo to local GOT entries,
not global ones.

I'm pretty certain this is the bug I fixed on mainline with:

    http://gcc.gnu.org/ml/gcc-patches/2006-10/msg01451.html

(The problem being that weakrefs are an odd case: they're weak,
but !TREE_PUBLIC.)

The patch applies cleanly to 4.2, and I've attached it here for
convenience.  Aaron, could you confirm it fixes the bug you're seeing?
(Also, please could you close the binutils bug?  The assembly code is,
as you suspected, invalid.)
