commit 9536661c6e8045f810cd227a7d676eaff19bf1b8
Author: Joseph Myers <joseph@codesourcery.com>

Fix -Wundef warnings in elf/tst-execstack.c.
To remove -Wno-error=undef, we need to fix the remaining cases where
there are -Wundef warnings in the testsuite. One of those places is
in elf/tst-execstack.c.
tst-execstack.c tests USE_PTHREADS with #if. nptl/tst-execstack.c
defines USE_PTHREADS to 1 before including ../elf/tst-execstack.c,
while elf/tst-execstack.c, when compiled directly, leaves it
undefined.
This patch adds a setting of CPPFLAGS-tst-execstack.c to
elf/Makefile. An alternative approach would be to rename
tst-execstack.c to tst-execstack-main.c and have two different
tst-execstack.c files include it, each with an appropriate
USE_PTHREADS #define.
Tested for x86_64.
* elf/Makefile [$(have-z-execstack) = yes]
(CPPFLAGS-tst-execstack.c): New variable.
