Well, this has been reported:

  http://sourceware.org/ml/libc-alpha/2014-01/msg00351.html
  https://sourceware.org/bugzilla/show_bug.cgi?id=16475

I was hoping it would be fixed in time for 2.19, but it seems it won’t
happen.

If it’s not too difficult to skip just those tests that require reverse
lookup, that’s the best thing.  Otherwise just #:tests? #f.  (Either
