getopt-gnu: add another test
Ensure that POSIXLY_CORRECT does not interfere with optional argument
behavior; older BSD implementations botched this.
* tests/test-getopt_long.h (test_getopt_long_posix): New test, to
guarantee behavior relied on by m4.
* tests/test-getopt.c (main): Use it.
* modules/getopt-posix-tests (Depends-on): Add setenv.
See http://lists.gnu.org/archive/html/bug-m4/2006-09/msg00028.html.
