	(struct bfd_mach_o_note_command): New.
	(struct bfd_mach_o_build_version_tool): New.
	(struct bfd_mach_o_build_version_command): New.
	(bfd_mach_o_read_version_min): Don't split version into
	a few fields. Rename reserved to sdk.
	* mach-o.c (bfd_mach_o_read_version_min): Don't split version into a
	few fields. Rename reserved to sdk.
