* gold-threads.h (class Initialize_lock): Define. * gold-threads.cc (class Initialize_lock_once): Define. (initialize_lock_control): New static variable. (initialize_lock_pointer): New static variable. (initialize_lock_once): New static function. (Initialize_lock::Initialize_lock): Define. (Initialize_lock::initialize): Define. * target-select.h: Include "gold-threads.h". (class Target_selector): Add lock_ and initialize_lock_ fields. Don't define instantiate_target, just declare it. * target-select.cc (Target_selector::Target_selector): Initialize new fields. (Target_selector::instantiate_target): Define. * descriptors.h: Include "gold-threads.h". (class Descriptors): Add initialize_lock_ field. * descriptors.cc (Descriptors::Descriptors): Initialize new field. (Descriptors::open): Use initialize_lock_ field * errors.h (class Errors): Add initialize_lock_ field. * errors.cc (Errors::Errors): Initialize new field. (Errors::initialize_lock): Use initialize_lock_ field. * powerpc.cc (class Target_selector_powerpc): Remove instantiated_target_ field. In do_recognize call instantiate_target rather than do_instantiate_target. In do_instantiate_target just allocate a new target. * sparc.cc (class Target_selector_sparc): Likewise.
