Add support for ELF files which contain multiple reloc sections which all target the same section.
* elf-bfd.h (struct elf_backend_data): Add new fields:
init_secondary_reloc_section, slurp_secondary_reloc_section,
write_secondary_reloc_section.
(_bfd_elf_init_secondary_reloc_section): Prototype.
(_bfd_elf_slurp_secondary_reloc_section): Prototype.
(_bfd_elf_write_secondary_reloc_section): Prototype.
* elf.c ( bfd_section_from_shdr): Invoke the new
init_secondary_reloc_section backend function, if defined, when a
second reloc section is encountered.
(swap_out_syms): Invoke the new symbol_section_index function, if
defined, when computing the section index of an OS/PROC specific
symbol.
(_bfd_elf_init_secondary_reloc_section): New function.
(_bfd_elf_slurp_secondary_reloc_section): New function.
(_bfd_elf_write_secondary_reloc_section): New function.
(_bfd_elf_copy_special_section_fields): New function.
* elfcode.h (elf_write_relocs): Invoke the new
write_secondary_relocs function, if defined, in order to emit
secondary relocs.
(elf_slurp_reloc_table): Invoke the new slurp_secondary_relocs
function, if defined, in order to read in secondary relocs.
* elfxx-target.h (elf_backend_copy_special_section_fields):
Provide a non-NULL default definition.
(elf_backend_init_secondary_reloc_section): Likewise.
(elf_backend_slurp_secondary_reloc_section): Likewise.
(elf_backend_write_secondary_reloc_section): Likewise.
(struct elf_backend_data elfNN_bed): Add initialisers for the new
fields.
* configure.ac (score_elf32_[bl]e_vec): Add elf64.lo
* configure: Regenerate.
