Don't rely on a pregenerated copy, as it may not be noticed by someone changing

The correct form of this would be CONFIG += ordered, TEMPLATE is only used to
specify the type of project (app, lib, etc) to build.

However: as has been evidenced by the incorrect version being used here, ordered

interdependencies.

This also makes the Qt 4 packages depend on the Qt 5 package (for the daemon
implementation).

For the time being, Qt 4 declarative/tests are still built, and the Qt 4 tests
package is not co-installable with Qt 5.
