(check_nocrossrefs): Call it.
(check_nocrossref): Interate over h->refs here instead of..
(check_refs): ..here. Pass in the symbol name, section, and bfd
rather than hash_entry pointers.
(struct check_refs_info): Keep symbol name rather than hash entry.
Remove "same".
(check_reloc_refs): Tweak for above changes in check_refs_info.
Only report references to section syms when symname is NULL to
prevent duplicate messages for the same reloc.
