	* oacc-init.c (acc_init): Remove !cached_base_dev condition on call
	to gomp_init_targets_once.
	(acc_set_device_type): Remove !cached_base_dev condition on call to
	gomp_init_targets_once, move call to before acc_device_lock acquire,
	to avoid deadlock.
	(acc_get_device_num): Remove !cached_base_dev condition on call to
	gomp_init_targets_once.
	(acc_set_device_num): Likewise.
