Title:
fontconfig initialization spends most of its time parsing XML

Bug description:
While profiling the startup of QML apps on the BQ E4.5 phone (armhf) I
noticed that a significant amount of time (around 35ms) was spent solely on
parsing the XML configuration files in /etc/fonts/conf.d/
There seems to be around 40 files on Ubuntu Phone in that directory.
