Code review comment for lp://staging/~thomas-voss/dbus-cpp/enable-dual-landings

13:04 <sil2100> The only problem I see so far is with the versioning
13:05 <sil2100> Currently the train does not support dual-landing with two different
                versioning schemes
13:06 <sil2100> And when building for instance dbus-cpp with your script, the package
                version for both xenial and vivid will be 5.0.0, but the contents inside
                will have 4.3.0 for vivid and 5.0.0 for xenial
13:06 <sil2100> Meaning that the package version is lying and trying to tell
                vivid-overlay users that it's shipping a different version

Sadly, I'm not sure if this could be done from override_dh_auto_clean as the rest. For now the only idea I have is to support such cases in the CI Train, but that's just my first guess.
