It might require reinventing the logic used by the ports system 
Makefiles.  Or maybe there's a way to run make config-recursive but get 
dialog to immediately cancel any config screens that appear (redirect 
input from /dev/null?).  Detect whether the output of that is not empty.

'make config-recursive' was already mentioned, but portupgrade has the 
-c and -C options, and running all the config screens before starting a 
build is automatic for portmaster.
