Application aren't supposed to update the font cache. Package 
Installation procedure is supposed to do this.

Even reading installed fonts list is meaningless, because the package 
builder has no fonts installed, and such list is meaningless.


The right solution is to either have this as an explicit configuration 
option: --disable-update-system-fonts,

or to remove fontconfig altogether.


I understand that you keep in mind people who will just install manually 
and not update fonts. But it is mostly built by package infrastructure. 
So maybe --disable-update-system-fonts approach is appropriate.
