* elf-eh-frame.c (ENSURE_NO_RELOCS): Disregard R_*_NONE relocs.

(_bfd_elf_discard_section_eh_frame): Don't discard duplicate CIEs
	on a relocatable link.  Comment typos.
	* elf.c (_bfd_elf_link_hash_newfunc): Assign elements of structure
	in the order they are declared.  Clear elf_hash_value too.
	(_bfd_elf_link_hash_table_init): Likewise assign in order.  Clear
	eh_info and tls_segment.
	* elflink.h (elf_link_input_bfd <emit_relocs>): Keep reloc offsets
	sorted when discarding relocs by turning them into R_*_NONE.

	* libbfd.c (warn_deprecated): Comment spelling.
	* po/SRC-POTFILES.in: Regenerate.
