[Fontconfig] Is there a way to set the cache directory using environment variables?

Doesn't work. Looking at the code it seems like XDG_CACHE_HOME is only handled if
there are no cache dirs in the config:

    if (config->cacheDirs && config->cacheDirs->num == 0) { 
         ...
         prefix = FcConfigXdgCacheHome ();
         ...
    }

The above if statement likely evaluates to FALSE for the MSYS2 build because
MSYS2 does define a cache directory but of course I don't want to use that because
it relies on the MSYS2 infrastructure...
