modifying the makefile.mk in scp2/util, for instance for adding a new module to
the setup, does not result in a rebuild on the next dmake. Instead, nothing is
built here.

Since "dmake -u" is not supported in OOo's build env (though it's supposed to
build everything in the current directory from scratch, ignoring dependencies),
the only feasible workaround is to delete the complete output tree, and build
the whole project - which is somewhat oversized and cumbersome.

I suggest adding makefile.mk to the dependecy list.

P4, since this is probably not really commonly encountered.
