tst-minsigstksz-1.c: Return EXIT_UNSUPPORTED for GCC 4.9 or older

Since ATOMIC_INT_LOCK_FREE in GCC 4.9 is defined as

 #define ATOMIC_INT_LOCK_FREE                    \
  __atomic_type_lock_free (atomic_int)

GCC 4.9 fails to compile tst-minsigstksz-1.c:

tst-minsigstksz-1.c:45:6: error: missing binary operator before token "("
 # if ATOMIC_INT_LOCK_FREE != 2
      ^

Change tst-minsigstksz-1.c to define TEST_ATOMIC_OPS to 0 for GCC 4.9 or
older.
