I was able to build the QML for 'XmlListModel' by making 'qtdeclarative'
a dependency of 'qtxmlpatterns' instead of the opposite (and the QML is in
the 'qtxmlpatterns' package).

Rebuilding the required Qt packages and 'monero-gui' and running it
worked fine. However I'm not too familiar with the Qt packages, so does
someone think this approach could cause problems in some of them?


Here's the patch I used:
