Check pie_enabled target in PIC tests

We need to check pie_enabled target in PIC tests to support GCC where
PIE is enabled by default when configured with --enable-default-pie.

	PR testsuite/70150
	* gcc.dg/20020312-2.c (dg-additional-options): Set to "-no-pie"
	for pie_enabled target.
	* gcc.dg/uninit-19.c: Check pie_enabled for PIC.
	* gcc.target/i386/pr34256.c: Likewise.
