	* mach-o.c (bfd_mach_o_make_bfd_section): Use the standard ELF name
	.eh_frame for __TEXT.__eh_frame so that it is recognized by gdb.
	Use shorter sections name for well known sections.
	(bfd_mach_o_scan_read_dylinker): Only put dylinker name in the
	section content.
	(bfd_mach_o_scan_read_segment): Use shorter sections name for
	well known segments.
	(bfd_mach_o_scan_read_command): Ignore some new commands.
	(bfd_mach_o_openr_next_archived_file): Use more descriptive names
	for members filename.
	(bfd_mach_o_fat_extract): New function to easily extract members
	of a fat binary.
	* mach-o.h (bfd_mach_o_load_command_type): Add new constants.
	(bfd_mach_o_dylinker_command): Fix comment and reindent.
	(bfd_mach_o_fat_extract): New prototype.
