Handle in-tree builds without copying.

Make dependency analysis with source rst and "intermediate" rst work.

Make sure your copying gets the timestamps right.

Make Sphinx dependency analysis look at the right copies depending on
in-tree vs. out-of-tree. Generally make sure it doesn't confuse Sphinx's
own dependency analysis.

The stuff I didn't think of.

Sure, it's all supposed to be basic Makefile stuff, but don't make the
mistake of thinking just one invocation of 'cp' will solve all the
problems. It all adds to the complexity we were trying to avoid when
dumping DocBook. It adds to the complexity of debugging stuff. (And hey,
there's still the one rebuilding-stuff-for-no-reason issue open.)

If you want to keep the documentation build sane, try to avoid the
Makefile preprocessing. And same old story, if you fix this for real,
even if as a Sphinx extension, *other* people than kernel developers
will be interested, and *we* don't have to do so much ourselves.


BR,
Jani.
