AFAICT cross-compiling amd64 on a i386 machine isn't supported yet. I ran into a similar problem when I upgraded an i386 machine to amd64. I thought I could just set CPUTYPE=athlon-64 and buildworld would do the right thing. Apparently not. 

I haven't bothered to try building i386 on an amd64 box though. Maybe you'll have better luck with that.
