You can use the following to edit the project data in your build  
environment:

$ darwinxref edit 9G55 ppp

You want to enter:

	environment = {
		RC_ARCHS = i386;
	};

... and then save/quit.

You can verify the archs are set with:

$ darwinxref environment ppp

This is a known problem of arch linking to Foundation. It looks like  
you just need an arch that spits out "i386" or whatever, you can  
replace it with a shell script that runs "uname -m".  Look for arch  
under the BuildRoot directory and replace it with the script.
