Extended the testsuite to force threads, so that __gthread_active_p path is on,
we still get segfaults on deallocate_global_thread-1.cc 

Backtrace is in __gthread_key_delete(_M_key), _M_key is 0 at this point.

    ~__freelist()
    {
      if (_M_thread_freelist_array)
    {
      __gthread_key_delete(_M_key);
      ::operator delete(static_cast<void*>(_M_thread_freelist_array));
      _M_thread_freelist = 0;
    }
    }

since the _M_thread_freelist setting to 0 is done afterward, I'm afraid this is
still fragile and mt_deallocate still have pending issues.
