 *  Test that pthread_attr_destroy()
 *  shall destory a thread attributes object.  An implementation may cause
 *  pthread_attr_destroy() to set 'attr' to an implementation-defined invalid
 *  value.
 *
 * Steps:
 * 1.  Initialize a pthread_attr_t object using pthread_attr_init()
 * 2.  Destroy that initialized attribute using pthread_attr_destroy()
 * 3.  Using pthread_attr_create(), pass to it the destroyed attribute. It
 *     should return the error EINVAL, the value specified by 'attr' is
 *     is invalid.
