convert to_supports_evaluation_of_breakpoint_conditions

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

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