I do not believe that rpm's stock configuration supports cross-building to a 
different architecture.  The --target parameter only sets the architecture 
label on the resulting rpms, and not much more.

Cross-compilation is not trivial to set up.  You must install, beforehand, 
the i386 build of every library that your software compiles against, and you 
must know, beforehand, what they are.  Then, you'll need to arrange, 
somehow, for the software's configuration script and makefile pass the -m32 
option to gcc.

It's rather unlikely that freetype's rpm and configure script implements all 
of this.
