(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. (bfd_mach_o_read_command): Handle LC_VERSION_MIN_TVOS, LC_NOTE, LC_BUILD_VERSION. (bfd_mach_o_read_note): New. (bfd_mach_o_read_build_version): New. PR 23728 binutils* od-macho.c (printf_version): New. (dump_load_command): Use it to print version. Print sdk version. Print version info for watchOS and tvOS. Print LC_NOTE, LC_BUILD_VERSION. (dump_buld_version): New. (bfd_mach_o_platform_name): New (bfd_mach_o_tool_name): New * mach-o/external.h (mach_o_nversion_min_command_external): Rename reserved to sdk. (mach_o_note_command_external): New. (mach_o_build_version_command_external): New. * mach-o/loader.h (BFD_MACH_O_LC_VERSION_MIN_TVOS): Define.
