    Fix -Wundef warnings in elf/tst-execstack.c.
c6d234
    
c6d234
    To remove -Wno-error=undef, we need to fix the remaining cases where
c6d234
    there are -Wundef warnings in the testsuite.  One of those places is
c6d234
    in elf/tst-execstack.c.
c6d234
    
c6d234
    tst-execstack.c tests USE_PTHREADS with #if.  nptl/tst-execstack.c
c6d234
    defines USE_PTHREADS to 1 before including ../elf/tst-execstack.c,
c6d234
    while elf/tst-execstack.c, when compiled directly, leaves it
c6d234
    undefined.

c6d234
    This patch adds a setting of CPPFLAGS-tst-execstack.c to
c6d234
    elf/Makefile.  An alternative approach would be to rename
c6d234
    tst-execstack.c to tst-execstack-main.c and have two different
c6d234
    tst-execstack.c files include it, each with an appropriate
c6d234
    USE_PTHREADS #define.

    Tested for x86_64.

c6d234
            (CPPFLAGS-tst-execstack.c): New variable.
