Because of changes in Qt Base, packages using qplatformsupport from private headers need to add additional dependency.

From Debian bug report:
---
This comes from QPlatformSupport stuff which creates a static library that
needs this linking.

It also happens that QPlatformSupport is private stuff, so there is really no
way to solve this but either stop using private stuff or helping upstream to
make QPlatformSupport public (which would be really helpful). This will in
turn mean that it will become a dynamic lib and this bug can be fixed.
