Add a way to tell fc-query to read fontconfig files outside its default tree
The fonts autodep generator in rpm, that was written by Behdad, basically just calls
$fcquery --format '%{=pkgkit}' "${fn}"
(it's in /usr/lib/rpm/fontconfig.prov)
So at it is written, it will compute query output based on the fontconfig configuration of the host system, ignoring the fontconfig files which are being installed with the font files in the build root.
It would be trivial for rpm to tell fc-query where those files are (that's just passing the /etc/fonts location in the buildroot). However, there is no flag in fc-query to receive this info
Please add such a flag
