I agree. That's the reason why I started this entire thread. Although I'd
rather see some sort of a search order.
You could make this a configurable option.

--enable-relative-path[=PATH]	defaults to ./fonts/

e.g.
/path/to/binary

If fontconfig was configured with above option, you would look for the
fonts.conf file in /path/to/binary/fonts
If nothing is found there, you can still look for the file in --sysconfdir
and/or /etc/fonts.
I'm not really sure why fontconfig has to look for the file in only one place
anyway...
