  Always compile the all versions of the hashlib algorithm modules when Python
  was compiled with Py_DEBUG defined.  Otherwise the builtins are not compiled by
  default for many developers due to OpenSSL being present, making it easier for
  bugs to slip by.  A future commit will add test code compare the behaviors of
  all implementations when they are all available.
