* elf-bfd.h: Formatting.
(_bfd_elf_map_sections_to_segments): Declare.
* elf-eh-frame.c (_bfd_elf_discard_section_eh_frame_hdr): Don't
clear program_header_size.
* elf.c (get_program_header_size): Move. Don't use or set saved
program_header_size here.
(elf_modify_segment_map): New function. Split out from..
(assign_file_positions_for_load_sections): ..here. Assert
header size is correct. Remove dead code.
(_bfd_elf_map_sections_to_segments): Rename from
map_sections_to_segments. Make global. Use get_program_header_size
when we need estimate of header size. Call elf_modify_segment_map.
Set program_header_size.
(print_segment_map): Delete.
(_bfd_elf_sizeof_headers): If segment_map available, get the
actual size.
* elf32-arm.c (elf32_arm_symbian_modify_segment_map): Make safe
for calling more than once.

* Makefile.am (ELF_DEPS): Define. Use in emul file deps. Fix
many ELF emul file deps that incorrectly said they needed elf32.em
instead of generic.em. Add genelf.em as required.
* Makefile.in: Regenerate.
* ldlang.c (lang_process): Call ldemul_finish before
lang_check_section_addresses.
