[oi-dev] QT5.8 alpha1 testing build

No offense taken ;)
I agree with you that we should stick with Qt4 for now and that I will
provide Qt5 alongside (in /usr/bin/qt/5.8) as experimental package for
testing.

I've spun a testing build of VirtualBox last week end:
- one target calling dtrace with no probe had to be removed from a Makefile,
- vboxusb does not work of course since I did not apply your fixes,
- it can only be run as root due to a plugin load permission issue in Qt,
- the keyboard input does not work for some input widgets.

I could boot a Firefly image in it.

Anyway you are correct that we should do not waste more time on Qt5
since you proved that Qt4 offers better support right now.
We will see next year if/when Qt5 is required and in better shape on
OI (hopefully because we upstreamed patches :D).

Kind regards

Aurelien
