bfd_merge_private_bfd_data tidy
bfd_merge_private_bfd_data and _bfd_generic_verify_endian_match are linker functions, so move them to linker.c. bfd/ * Makefile.am (LIBBFD_H_FILES): Update. * doc/Makefile.am (LIBBFD_H_DEP): Likewise. * cpu-sh.c (sh_merge_bfd_arch): Move to.. * elf32-sh.c: ..here, and make static. * elf32-arc.c (arc_elf_merge_private_bfd_data): Delete extraneous error. * elf32-cris.c (cris_elf_merge_private_bfd_data): Don't call _bfd_generic_verify_endian_match. * elf32-microblaze.c (microblaze_elf_merge_private_bfd_data): Delete.
