* elf32-s390.c (allocate_dynrelocs): For undef weak syms with

	non-default visibility, a) don't make them dynamic, b) discard
	space for dynamic relocs.
	(elf_s390_relocate_section): Initialize the GOT entries and skip
	R_390_{8,16,32}/R_390_PC{16,16DBL,32DBL,32} for weak undefined
	symbols with non-default visibility.
	* elf64-s390.c: Likewise.
