Here's the revised patch.  I've cleaned up
sh_elf_link_hash_newfunc as requested, and remade the whole patch
now that the tls support has been merged in.

The code in allocate_dynrelocs and sh_elf_finish_dynamic_symbol will
almost certainly require extra work when tls is extended to sh64, but
I've treated that as out of the scope of this patch - it requires an
understanding of the interraction between datalabel and tls.
