Instead of looking at `dist` and DIST_DIR directly in the Kati Build
step, always write out information about every call to dist, then create
the rules in another ckati run.
So instead of having:
dist: <goal> -> <dist> -> <output>
\______________↑
nodist: <goal> -----------> <output>
Always use another phony target in the Kati Build step:
<goal> ---> <output>
\----> _dist_<goal>
Then in the packaging step (which is much faster), choose between dist
and no dist:
dist: _dist_<goal> -> <dist> -> <output>
nodist: _dist_<goal>
