Rename the user-visible tools to names that do not conflict with Qt 4 installations.
Recommendation from Simon on the mailing list is to prefix all tools with "qt5-". (e.g., qt5-qmake, qt5-moc, qt5-uic)
Tools affected are tools that are installed globally and run by the user, but not considered applications per se:
- Definitely: qmake
- Definitely not to be included: Creator, Assistant, Linguist, qdbus
