There are techniques to do lazy updates in makefiles. They involve
stamp files and/or recursive make invocations. Not pretty, and more
complex than the rules gnulib currently produces, but they work, and
they do not continuously need to recreate temporary files.
I agree that we should document the respective techniques and their
exact semantics and portability issues better in either of
auto{conf,make}.texi.

This should not be an issue with above.
