debian/rules:6: recipe for target 'binary-indep' failed
make: *** [binary-indep] Error 2
dpkg-buildpackage: error: fakeroot debian/rules binary-indep subprocess returned exit status 2
--------------------------------------------------------------------------------

The build was made with "dpkg-buildpackage -A" in my autobuilder
but it also fails in reproducible builds:

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

Thanks.
