Dear maintainer:

dpkg-buildpackage: error: fakeroot debian/rules binary-arch subprocess returned exit status 2
--------------------------------------------------------------------------------

The build was made with "dpkg-buildpackage -B" in my autobuilder.
Most probably, it also fails here in reproducible builds:

https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/happy.html

[ Note: There has been a recent change in debhelper behaviour, the current
  behaviour is the intended one. See Bug #903133 for details ].

Thanks.
