Please backport this patch into qtbase

[Martin Klapetek]

There's an issue with QCoreApplication::libraryPaths() which always appends QLibraryInfo::location(QLibraryInfo::PluginsPath) first and only then it reads/appends QT_PLUGIN_PATH contents. In K/Ubuntu, QLibraryInfo::location(QLibraryInfo::PluginsPath) returns "/usr/lib/x86_64-linux-gnu/qt5/plugins" by default.

This makes effectively all custom development outside of /usr impossible if there is also a system version of some plugin as Qt will /always/ load the system one rather than the one that's being worked on (and installed to say /opt), even with correct QT_PLUGIN_PATH set.

This is fixed in Qt but apparently in 5.6 only, so I'd like to request backporting this following commit to Qt 5.5 for wily:
