[3/6] nvptx testsuite patches: stdio

[Bernd Schmidt <bernds at codesourcery dot com>]

Some tests use stdio functions which are unavaiable with the cut-down 
newlib I'm using for ptx testing. I'm somewhat uncertain what to do with 
these; they are by no means the only unavailable library functions the 
testsuite tries to use (signal is another example). Here's a patch which 
deals with parts of the problem, but I wouldn't mind leaving this one 
out if it doesn't seem worthwhile.

	gcc/testsuite/
	* lib/target-supports.exp (check_effective_target_stdio): New
	function.
	* gcc.c-torture/execute/gofast.c (fail): Don't fprintf on nvptx.
	* gcc.dg/torture/matrix-1.c: Require stdio.
	* gcc.dg/torture/matrix-2.c: Require stdio.
	* gcc.dg/torture/matrix-5.c: Require stdio.
	* gcc.dg/torture/matrix-6.c: Require stdio.
	* gcc.dg/torture/transpose-1.c: Require stdio.
	* gcc.dg/torture/transpose-2.c: Require stdio.
	* gcc.dg/torture/transpose-3.c: Require stdio.
