SH New PLT code

Thanks very much for submitting this patch.  No-one has posted any
objections to it, so I have approved it and applied it to the sources.

Note - I made two changes to the patch.  I added a comment at the
start, explaining why the PLT entries have changed, and I kept the old
PLT entries (but commented out), in case the patch raises problems and
we need to go back to the old method.

Please do this.

Approved and applied.
