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.

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.
