	* elf32-i386.c (allocate_dynrelocs): Don't allocate dynamic
	relocation entries for weak undefined symbols with non-default
	visibility.
	(elf_i386_relocate_section): Initialize the GOT entries and
	skip R_386_32/R_386_PC32 for weak undefined symbols with
	non-default visibility.

	* elfxx-ia64.c (allocate_fptr): Don't allocate function
	descriptors for weak undefined symbols with non-default
	visibility.
	(allocate_dynrel_entries): Don't allocate relocation entries
	for symbols resolved to 0.
	(set_got_entry): Don't install dynamic relocation for weak
	undefined symbols with non-default visibility.
	(set_pltoff_entry): Likewise.

	* elflink.h (elf_fix_symbol_flags): Hide weak undefined symbols
	with non-default visibility.
	(elf_link_output_extsym): Don't make weak undefined symbols
	with non-default visibility dynamic.
