Well, those dependent ports will just be built without universal  
support. (This is the same for all variants and all ports: if you ask  
for a variant that does not exist, no error is produced; the port is  
simply built without that nonexistent variant.)

If the port you are ultimately trying to build does depend on a  
universal version of that dependent port which has no universal  
support, then you will likely get errors at that point.
