Bug#607281: lintian: errors for unneeded targets

[Damian Johnson <atagar1@gmail.com>]

Package: lintian
Version: Lintian v2.2.17ubuntu1.1

Hi, I'm packaging a python application for debian and running into an
issue with lintian errors for unneeded build targets:

E: tor-arm source: debian-rules-missing-required-target binary
E: tor-arm source: debian-rules-missing-required-target binary-arch
E: tor-arm source: debian-rules-missing-required-target binary-indep
E: tor-arm source: debian-rules-missing-required-target build
E: tor-arm source: debian-rules-missing-required-target clean

This concerns both the version of lintian on my local system (ubuntu)
in addition to the debian upload ftp. Including the following in my
rules file makes lintian happy, but it's not doing anything useful for
the build:

build:
       echo "nothing to build"

binary-indep:
       echo "nothing to binary-indep build"

binary:
       echo "nothing to binary build"

binary-arch:

clean::
       dh_clean

Cheers! -Damian
