Unfortunately the Qt developers have bigger problems than the above to fix.
Qt 5.4 as it exists in the 5.4 branch at the moment is unbuildable
(despite their blocking CI system).

Please see http://build.kde.org/view/FAILED/job/qt5_master_qt5/168/console
for why.
Could someone prod them into fixing their build?

This means that no KDE project can depend on Qt 5.4 at this time.
