Code review comment for lp:~raof/mir/buildsystems-are-the-worst

Hm. Ok, so http://s-jenkins.ubuntu-ci:8080/job/mir-mediumtests-runner-mako/2503/console proves that this does, indeed, fix the problem of linking against all the things.

And http://s-jenkins.ubuntu-ci:8080/job/mir-mediumtests-runner-mako/2506/console shows that the remaining problem is that we don't upgrade libmirplatform-graphics-android. I've got a branch of the testrunner that'll fix that, but only once Mir is parallel installable with old versions.

So I'll merge in Alan's versioning revert and then this branch should pass.
