* 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.
