Build fixes

Fix moc when moc-qt4 is qt4 moc but moc is qt5 one
Do not add -fPIE everywhere, just -fPIC to qt5
No distro ships moc-qt5 but make it work in case someone would
Use qtchooser if available
Bring PIC back to the toplevel, still have linking errors tohugh :-/
Allow to enable Qt5 support only with CMake >= 2.8.8
We are not compiling an executable
If qmake gives us a Qt5 qmake try with qmake4 and qmake-qt4
Make it build with autotools
Bring changes from the qt4 dir
Fix indent
Merge remote-tracking branch 'origin/qt5'
