One potential problem I see (I haven't looked at your changes, sorry,
holiday and lack of time) - is in the behavior of dependencies. Say
that something in qtbase is deprecated, but not yet removed from all
submodules (due to a lack of urgency, proliferation of use, whatever)
--- that will then block the build of the submodules, but not qtbase.

Maybe -Wno-error=deprecated would be a good idea?
