* elf32-arm.c (elf32_arm_modify_segment_map): New function.
(elf32_arm_additional_program_headers): Likewise. (elf_backend_modify_segment_map): Define. (elf_backend_additional_program_headers): Likewise. (elf32_arm_symbian_modify_segment_map): Use elf32_arm_modify_segment_map. * binutils/readelf.c (get_arm_segment_type): New function. (get_segment_type): Use it. * arm.h (PT_ARM_EXIDX): Define.
