* elf32-i386.c (allocate_dynrelocs): For undef weak syms with
non-default visibility, a) don't make them dynamic, b) discard
space for dynamic relocs.
* elf64-x86-64.c (allocate_dynrelocs): Likewise.
* elf32-ppc.c (allocate_dynrelocs): For undef weak syms with
non-default visibility, a) don't allocate plt entries, b) don't
allocate .got relocs, c) discard dyn rel space,
(ppc_elf_relocate_section): d) don't generate .got relocs, e)
don't generate dynamic relocs.
* elf64-ppc.c (allocate_dynrelocs): As above.
(ppc64_elf_relocate_section): As above.
