Add the ability to the BFD library to read build-ids from core flies.
* elf-bfd.h (elf_backend_data) <elf_backend_core_find_build_id>:
New field.
(_bfd_elf32_core_find_build_id, _bfd_elf64_core_find_build_id):
New functions.
(elf_read_notes): Add declaration.
* elf.c (elf_read_notes): Move elf-bfd.h.
(_bfd_elf_core_find_build_id): New function.
(bfd_section_from_phdr): Scan core file PT_LOAD segments for
build-id if none is known.
(elf_parse_notes): For core files, scan for notes.
* elfcore.h (elf_core_file_matches_executable_p): If both
BFDs have identical build-ids, then they match.
(_bfd_elf_core_find_build_id): New function.
* elfxx-target.h (elf_backend_core_find_build_id): Define.
(elfNN_bed): Add elf_backend_core_find_build_id.
