${FALSE}, and the package admin is responsible for creating them himself
prior to the installation of a package.
Include it in bsd.prefs.mk to allow their use much earlier in Makefiles,
and try to use the variable references instead of directly invoking the
programs in bsd.prefs.mk and bsd.pkg.mk where possible.
