Unfortunately with those commits I get this when compiling for a
64-bit target:

It turns out that with Arnd's patches we now get "-mcpu=powerpc64" on
the command line, and that means that gcc *doesn't* put "-mppc64" the
as command line, and as barfs on the 64-bit instructions.  That's
presumably a gcc bug, but we'll have to work around it.  I think the
best thing is just to not put the -mcpu=powerpc64 in CFLAGS when no
specific CPU is selected.

I dropped the patch and re-pushed my tree w/o it.

Let me know if you have any issues.
