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.
