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.
