The failures of https://codereview.qt-project.org/#/c/180231/ and 
https://codereview.qt-project.org/#/c/180232/ happened on Ubuntu Touch 

That platform is not part of 5.9 CI anymore. So as far as I understand 
it hasn't been tried if the patches could successfully integrate into 5.9?

Disabling cross-compilation of QtDBus would break a lot of users. 
(Including Qt for Device Creation builds.) So hopefully we can find some 
other way.
