* elf-bfd.h (struct elf_backend_data): Add
elf_backend_modify_program_headers. * elfxx-target.h (elf_backend_modify_program_headers): Define. (elfNN_bed): Init new field. * elf.c (elf_modify_segment_map): Remove comment. (assign_file_positions_for_load_sections): Only call elf_modify_segment_map for objcopy/strip. (assign_file_positions_except_relocs): Call elf_backend_modify_program_headers. * elf32-frv.c (elf32_frvfdpic_always_size_sections): Don't make .stack section. (elf32_frvfdpic_modify_segment_map): Delete. (elf32_frvfdpic_modify_program_headers): New. (elf_backend_modify_segment_map): Don't define. (elf_backend_modify_program_headers): Define. * elf32-bfin.c (elf32_bfinfdpic_always_size_sections): Don't make .stack section. (elf32_bfinfdpic_modify_segment_map): Delete. (elf32_bfinfdpic_modify_program_headers): New. (elf_backend_modify_segment_map): Don't define. (elf_backend_modify_program_headers): Define. * elfxx-ia64.c (elfNN_ia64_modify_program_headers): New function. Split out from.. (elfNN_ia64_modify_segment_map): ..here. (elf_backend_modify_program_headers): Define.
