This patch causes dg-require-effective-target to return early if the
test is already being skipped, saving some work.  There's already
similar code in dg-skip-if.

OK for trunk, and later for 4.6?

	* lib/target-supports-dg.exp (dg-require-effective-target): Return
	early if the test is already being skipped.

Ok.  Ok for 4.6.  I'm not a huge fan of upvar, but, you didn't create the problem, so, you don't have to fix it.
