(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.

	(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.

	* 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.
