[Qt-creator] New behavior or "Run Qmake" in 4.1.0

[Ronan Jouchet]

Hi.

The changelog for QtCreator 4.1.0 [1] mentions:

     Changed `Run Qmake` from `qmake -r`
     to `qmake && make qmake_all` for Qt 5

I couldn't find a linked QTBUG or discussion on the mailing list, so I'm 
asking here:

Could anyone detail the benefits brought by this change, and potential 
user-side caveats to avoid with the new behavior? It may be breaking 
incremental build for a project I'm working on.

Thanks.
