Re: PowerPC64: stub debug dump

Let's show the current stub as well as the previous one.  Of interest
is the current offset and a new field, id.  Check that the build
hash table traversal is in the same order as sizing traversal too.

	* elf64-ppc.c (struct ppc_stub_hash_entry): Add id.
	(struct ppc_link_hash_table): Add stub_id.
	(stub_hash_newfunc): Init id and symtype.
	(dump_stub): New function, extracted from..
	(dump_previous_stub): ..here.  Deleted.
	(ppc_build_one_stub): Sanity check stub id as well as offset.
	Show current stub as well as previous.
	(ppc_size_one_stub): Set stub id.
	(ppc64_elf_size_stubs): Init stub_id before traversal.
	(ppc64_elf_build_stubs): Likewise.
