elf: Add size_relative_relocs and finish_relative_relocs
On some targets, the DT_RELR section size can be computed only after all
symbols addresses can be determined. Set the preliminary DT_RELR section
size before mapping sections to segments and set the final DT_RELR section
size after regular symbol processing is done.
* elf-bfd.h (elf_backend_data): Add size_relative_relocs and
finish_relative_relocs.
* elf.c (_bfd_elf_map_sections_to_segments): Call
size_relative_relocs if DT_RELR is enabled.
* elflink.c (bfd_elf_final_link): Call finish_relative_relocs
after regular symbol processing is finished if DT_RELR is enabled.
* elfxx-target.h (elf_backend_size_relative_relocs): New.
(elf_backend_finish_relative_relocs): Likewise.
(elfNN_bed): Add elf_backend_size_relative_relocs and
elf_backend_finish_relative_relocs.
