I will leave it to an ARM maintainer to approve the patch, but:

I think it should be OK to require unreleased binutils, especially in
that it seems likely there will be a new binutils release before GCC 4.3
is out. The GCC Release Manager seems to have been distracted of late,
and while I hear that he plans to get back on the horse real soon, he's
still got 4.1.2 and 4.2.0 to get through the pipeline.
If we really want to concern ourselves about this, we could file a P1
bug against 4.3, nothing that we should do the horrible autoconf thing
if there has not yet been a binutils release.
