Also getting this when building for Ubuntu Xenial

The check was disabled on the 14th of January, commit 8330b99e01649e074cf80ab3490a8d0331789731

You can safely disable it with a patch if you want to build from version b2.

[Federico Ceratto (federico-ceratto)]

Patch ported to the Debian package. It builds successfully (e. g. https://mitaka-jessie.pkgs.mirantis.com/job/designate/5/ )
