[webkit-dev] Does Webkit support cross-compilation?

I am trying to get webkit/qt built for a PPC processor, using a cross- 
compiler.  I have Qt cross-compiled and running on the target machine.

When I try to build the webkti for the PPC, I get an error with  
dftables.  Apparently, the build routine cross-compiled it instead of  
building it for the host platform.  I am guessing that I did not set  
up something correctly.    Below is the output and the QMAKESPEC.  I  
don't see how to set it up to know about a cross-compilation.

Any suggestions is greatly appreciated.
