ld: Add -static-pie tests

Add -static-pie tests for DT_INIT_ARRAY, DT_FINI_ARRAY, DT_PREINIT_ARRAY
and IFUNC.

	* testsuite/config/default.exp (STATIC_PIE_LDFLAGS): New.  Set
	to "-static-pie" if target compiler supports it.
	* testsuite/ld-elf/elf.exp: Run -static-pie tests if
	$STATIC_PIE_LDFLAGS isn't empty.
	* testsuite/ld-ifunc/ifunc.exp: Likewise.
