As of yesterday, most ports' kernel Makefile templates (see
sys/arch/<PORT>/conf/Makefile.<PORT>) still have depedency lines 

	uipc_proto.o vfs_conf.o: Makefile

but vfs_conf.c is long gone, and uipc_proto.c doesn't have any #ifdef
dependencies at all, so it shouldn't need rebuilding after a `make config'.
Any reason not to remove these lines? Anyone want me to do it?

I dont know about other ports, but for the pmax (and mips), many (if
not all) of the explicitly-listed dependencies on the Makefile are
covered by defopt files. Anyone know of any reason not to remove such
dependency lines from Makefile.pmax? (or from other ports, at the
portmasters' discretion?)
