Hmmm, so do I, and in fact the arch/powerpc/boot/wrapper change now
seems to be unnecessary with my cross-compile setup (which has ld
2.16.1), whereas yesterday I'm sure it got errors.  Weird.

Chris, could you try just the following change (my previous patch
without the arch/powerpc/boot/wrapper change) and let me know if it
fixes things with the ld you use?

Paul.
