Look in .usr/src/Makefile.inc1 It's actually rather more complicated that just having clean as a dependency for buildworld/buildkernel. The idea is maximum safety and building something with the complexity of the operating system without knowledge of the state of EVERYTHING in the build is more dangerous, si the default for building wither the kernel or the world is to clean most everything up before starting. Just some honest paranoia. It's really ugly to build a new OS and discover that some stuff won't work. (Try living with a bad libc.) A corrupt kernel is even worse. R.
