* readsyms.cc (Read_symbols::incompatible_warning): New function.
(Read_symbols::requeue): New function. (Read_symbols::do_read_symbols): If make_elf_object fails because the target type is not configured, and the file was searched for, issue a warning and retry with the next directory. (Add_symbols::run): If the file has an incompatible format, and it was searched for, requeue the Read_symbols task. On error, release the object. * readsyms.h (class Read_symbols): Add dirindex_ field. Add dirindex parameter to constructor. Change all callers. Declare incompatible_warning and requeue. (class Add_symbols): Add dirpath_, dirindex_, mapfile_, input_argument_ and input_group_ fields. Add them to constructor. Change all callers. (class Read_script): Add dirindex_ field. Add it to constructor. Change all callers. * archive.cc (Archive::setup): Remove input_objects parameter. Change all callers. (Archive::get_file_and_offset): Likewise. (Archive::read_all_symbols): Likewise. (Archive::read_symbols): Likewise. (Archive::get_elf_object_for_member): Remove input_objects parameter. Add punconfigured parameter. Change all callers. (Archive::add_symbols): Change return type to bool. Check return value of include_member. (Archive::include_all_members): Likewise. (Archive::include_member): Change return type to bool. Return false if first included object has incompatible target. Set included_member_ field. (Add_archive_symbols::run): If add_symbols returns false, requeue Read_symbols task. * archive.h (class Archive): Add included_member_ field. Initialize it in constructor. Add input_file and searched_for methods. Update declarations. (class Add_archive_symbols): Add dirpath_, dirindex_, and input_argument_ fields. Add them to constructor. Change all callers. * script.cc: Include "target-select.h". (class Parser_closure): Add skip_on_incompatible_target_ and found_incompatible_target_ fields. Add skip_on_incompatible_target parameter to constructor. Change all callers. Add methods skip_on_incompatible_target, clear_skip_on_incompatible_target, found_incompatible_target, and set_found_incompatible_target. (read_input_script): Add dirindex parameter. Change all callers. If parser finds an incompatible target, requeue Read_symbols task. (script_set_symbol): Clear skip_on_incompatible_target in closure. (script_add_assertion, script_parse_option): Likewise. (script_start_sections, script_add_phdr): Likewise. (script_check_output_format): New function. * script.h (read_input_script): Update declaration. * script-c.h (script_check_output_format): Declare. * yyscript.y (file_cmd): Handle OUTPUT_FORMAT. (ignore_cmd): Remove OUTPUT_FORMAT. * fileread.cc (Input_file::Input_file): Add explicit this. (Input_file::will_search_for): New function. (Input_file::open): Add pindex parameter. Change all callers. * fileread.h (class Input_file): Add input_file_argument method. Declare will_search_for. Update declarations. * object.cc (make_elf_object): Add punconfigured parameter. Change all callers. * object.h (class Object): Make input_file public. Add searched_for method. (make_elf_object): Update declaration. * dirsearch.cc (Dirsearch::find): Add pindex parameter. Use it to restart search. * dirsearch.h (class Dirsearch): Update declaration. * options.h (class General_options): Add --warn-search-mismatch. * parameters.cc (Parameters::is_compatible_target): New function. * parameters.h (class Parameters): Declare is_compatible_target. * workqueue.cc (Workqueue::add_blocker): New function. * workqueue.h (class Workqueue): Declare add_blocker.
