New version, avoiding quadratic behavior and delayed expansion.

malloc: Run tests without calling mallopt [BZ #19469]

The compiled tests no longer refer to the mallopt symbol
from their main functions.  (Some tests still call mallopt
explicitly, which is fine.)

2016-06-28  Florian Weimer  <fweimer@redhat.com>

	[BZ #19469]
	* malloc/Makefile (CPPFLAGS): Compile tests with
	-DTEST_NO_MALLOPT.
	* test-skeleton.c (main): Only call mallopt if !TEST_NO_MALLOPT.
