I have a patch that fixes this issue like this:

if {[variant_isset universal]} {

Like Ryan, I had no issue uni-building with i386+x86_64 arches set, but
throwing ppc in the mix seems to mess things up. I'm also pretty sure my fix
is not the best way to approach, but I guess it's worth looking into _why_
it gets the build working...

I've attached the patch in case someone would like to use it...
