Dear maintainer:

debian/rules:4: 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.
Most probably, it also fails here in reproducible builds:

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

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

Thanks.
