convert to_static_tracepoint_marker_at

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

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