[4.2/4.1 PATCH]: testsuite gcc.target/i386/pr21291.c backport target selector

[Kaveh R. GHAZI]

As per:
http://gcc.gnu.org/ml/gcc-patches/2008-01/msg00467.html

I'm backporting the target selector that elides this test for ilp32 when
using -fpic/-fPIC.

Tested on i686-unknown-linux-gnu on 4.2 & 4.1 branches via "make check".

Okay for 4.2/4.1?

		Thanks,

	* gcc.target/i386/pr21291.c: Require nonpic or ! ilp32.
