[Fontconfig] fontconfig configure-generated libtool fails to find cross-compiled libs

[Leon Woestenberg]

Hello,

I fixed one bug in my arguments to configure but it didn't save the day. 
My cross-compiled "freetype-config" was giving out absolute paths, so I 
have created a script "freetype-config2" that calls "freetype-config 
--prefix=/myrootforfreetype/usr". When this script is used, it gives out 
the correct dirs etc.

However, I seem to have gotten stuck on an issue with libtool:

http://lists.debian.org/debian-embedded/2005/09/msg00030.html

How can I override the libtool being used (by fontconfig)?

Regards,

Leon.
