PR 10478:
* elf.c (bfd_section_from_shdr): Do not reject sparc binaries with
section headers containing sh_link values of SHN_BEFORE or
SHN_AFTER.
* elfcode.h (elf_object_p): Likewise.
readelf.c (get_elf_section_flags): Add support for SHF_EXCLUDE and
SHF_ORDERED.
(process_section_headers): Warn about out of range sh_link
values. When displaying detailed section header information
annote the SHN_BEFORE and SHN_AFTER values.
