Preserve machine dependent section header flags when reading ELF object file.
* elf-bfd.h (struct elf_backend_data): Add elf_backend_section_flags
field.
* elf.c (_bfd_elf_make_section_from_shdr): Call the
elf_backend_section_flags function.
* elf64-ia64.c (elf64_ia64_section_from_shdr): Delete flag conversion
code.
(elf64_ia64_section_flags): New function containing flag conversion
code.
(elf_backend_section_flags): Define to elf64_ia64_section_flags.
* elfxx-target.h (elf_backend_section_flags): Define.
(elfNN_bed): Initialize elf_backend_section_flags field.
