    Look for correct "ar" to cross-compile
    
    For some reason, autoconf doesn't by default have an "AC_PROG_AR" for
    this -- possibly it's assumed that any "ar" you have will work
    everyplace.
    
    Fixes bug 3909; found by sid77.
    
    This fixes a build issue first present in fdbdb4dc1500, but the bug
    (of not using a correct ar) has been in every Tor version ever: it
    just didn't matter until then.
