Theoretically the version check of the contribs should be the minimum we support for VLC 4 (6.2?). But that means it should be a "global" variable that each qt contrib can use. We may set this value in qt/rules.mak because the .mak seem to be included in alphabetical order. Otherwise it should be set in contrib/main.mak.

This can be done in a MR later.
