  Add support for GNU/Hurd to getentropy() Reuse the getentropy code for Linux on the Hurd, which has fallbacks for when the better interfaces are not present. And remove all the code that is not supported currently on the Hurd. Ideally the Hurd should get an equivalent interfaces that does not suffer from the same problems as /dev/urandom.
