IIRC mmap'ing files would break with 32-on-64, but I'd have to check up on the
details. I ended up passing MAP_32BIT to all linux-user mmap calla for
32-on-x86_64, but that doesn't work with -R.
But either way, this patch fixes an immediate build failure on ppc hosts for us
and should regardless be applied to 1.0-stable. I would also vote for adding it
to HEAD now and go for the removal of all linker scripts later, if we're sure
we don't have any regressions.
