[meta-freescale] meta-qt5 and WebKit2 examples?

[Erik Botö]

Hi all,

Ok, so I did another test. Qt 5.2.1 but using QtWebkit 5.1.1. This
works well for me on a nitrogen6x, and I'll probably use this as a
work-around for now.

FYI, there's a thread on qt-dev about this,
http://lists.qt-project.org/pipermail/interest/2014-April/011807.html
.

I had to do two minor backports in order to compile the older
qtwebkit, see below. I also saw that there were error building with
qtlocation, but I just disabled that since I'm not using it right now
anyway. It can probably be fixed as well though if you just look in to
it.
