	* Makeconfig (stack-align-test-flags): Set.
	* stdlib/Makefile (CFLAGS-tst-bsearch.c): Add
	$(stack-align-test-flags).
	* stdlib/tst-bsearch.c: Include tst-stack-align.h.
	(align_check): New var.
	(comp): Use TEST_STACK_ALIGN macro.
	(do_test): Fail if align_check != 1.
	* sysdeps/generic/tst-stack-align.h: New file.
	* sysdeps/i386/i686/Makefile (stack-align-test-flags): Add -msse.
