* 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.
