convert to_can_execute_reverse

2014-02-19  Tom Tromey  <tromey@redhat.com>

	* target-delegates.c: Rebuild.
	* target.c (update_current_target): Don't inherit or default
	to_can_execute_reverse.
	* target.h (struct target_ops) <to_can_execute_reverse>: Use
	TARGET_DEFAULT_RETURN.
	(target_can_execute_reverse): Unconditionally delegate.
