* libaout.h (struct aoutdata): Add q_magic_format to subformat
enum. * aout-target.h (MY_bfd_copy_private_bfd_data): Define as function if not already defined. Copy subformat information. (MY_text_includes_header): Define as 0 if not already defined. (MY(backend_data)): Use MY_text_includes_header rather than 0. (MY_final_link_callback): Rename from final_link_callback, and define only if MY_final_link_callback is not already defined. (MY_bfd_final_link): Rename use of final_link_callback to MY_final_link_callback. * aoutx.h (NAME(aout,some_aout_object_p)): Handle QMAGIC like ZMAGIC, but set the subformat to q_magic_format. Abort if the magic number if not recognized. (adjust_z_magic): Use QMAGIC if q_magic_format. * i386linux.c (MY_text_includes_header): Define as 1. (i386linux_bfd_final_link): New static function. (MY_bfd_final_link): Define as i386linux_bfd_final_link. * aoutx.h (translate_to_native_sym_flags): Check both section and output_section against sections of abfd.
