I built some other packages depending on 'qtdeclarative' and/or
'qtxmlpatterns' and I haven't seen any failure, so I pushed the patch as
3e10b2418dc0952c16053ccced4baba405facb6b.

[Message part 6 (text/plain, inline)]

In version 5.12.6 of the 'qtdeclarative' package, the
'lib/qt5/qml/QtQuick/XmlListModel' directory is missing (qtdeclarative
5.11.3 had it).

It causes run time issues; for example the 'monero-gui'
package builds fine but it fails to run:
