I've had this happen for a while but kept forgetting to post a pr.

If you define WITHOUT_GCC, a cc isn't created in 
/usr/obj/usr/src/tmp/usr/bin but if you go into the directory and do a 
symbolic link from clang, and restart make with -DNO_CLEAN it'll work 
and complete.  One of the programs hardcodes cc and doesn't check the 
environment, I forget which.
