	* elflink.c (_bfd_elf_link_record_dynamic_symbol): Clear the
	visibility bits if the symbol is undefined. Correctly handle
	weak undefined symbols with hidden and internal attributes.

	* elflink.h (elf_link_add_object_symbols): Always turn the
	symbol into local if it has the hidden or internal attribute.
