Nix - March 13, 2016, 3:16 p.m.
From: Nick Alcock <nick.alcock@oracle.com>

These tests do not link with libc, so cannot see __stack_chk_fail().

v3: Use $(no-stack-protector).

	* elf/Makefile (CFLAGS-filtmod1.c): Use $(no-stack-protector) for
	non-libc-linking testcase.
	(CFLAGS-filtmod2.c): Likewise.
	* stdlib/Makefile (CFLAGS-tst-putenvmod.c): Likewise.
	* sysdeps/x86_64/Makefile (CFLAGS-tst-quad1pie.c): Likewise.
	(CFLAGS-tst-quad2pie.c): Likewise.
