If only want to switch from 'some fonts' to 'no fonts', then the goal
should be to leave the individual font packages as 'bool' and only change
MENU_XORG_FONTS/XORG_FONTS to tristate.

However, that's currently not quite that simple because xorg-fonts provides
the dependencies. Hmmm, try this for the font packages:

ifdef PTXCONF_XORG_FONTS
PACKAGES-$(PTXCONF_XORG_FONT_<SOMETHING>) += xorg-font-<something>
endif

Then the packages should be skipped if XORG_FONTS is not selected in the
collection.
