libstdc++: Fix test failure due to -Wnonnull warnings

This test fails in the Fedora RPM build (but not elsewhere, for unknown
reasons). The warning is correct, we're passing a null pointer.

	* testsuite/tr1/8_c_compatibility/cstdlib/functions.cc: Do not pass
	a null pointer to functions with nonnull(1) attribute.
