	* elflink.h (elf_link_input_bfd): Zero the reloc instead of doing
	bfd_reloc_type_lookup (bfd, BFD_RELOC_NONE) as bfd_reloc_type_lookup
	doesn't accept BFD_RELOC_* on some targets, eg. hppa.

	* elf32-hppa.c (elf32_hppa_link_hash_entry): Remove plt_abs.
	(hppa_link_hash_newfunc): Likewise.
	(elf32_hppa_finish_dynamic_symbol): Likewise.
	(allocate_dynrelocs): Always allocate .got relocs if shared.
	(elf32_hppa_relocate_section): Output them too.  Similarly
	consolidate .plt reloc code, and no longer initialise .plt
	when a reloc is output.
	(elf32_hppa_finish_dynamic_symbol): Only initialise .plt entries
	when no reloc is output.
