* when enabled, configure check for "fonts" directory existence in following directories:
/usr/X11R6/lib/X11 /usr/X11/lib/X11 /usr/lib/X11
on _host_ system and if it exists it adds <dir> element to
/etc/fonts/fonts.conf
* update_font_cache postinst will then fail if host system has e.g.
/usr/lib/X11/fonts while the rootfs doesn't have it
* if you're installing fonts to other directories, you'll need to adapt
this EXTRA_OECONF to find them that's why it's in separate variable
[YOCTO #9155] - update_font_cache postinst failing with read-only filesystem
