[PATCH 2/3] build system: remove configure output in Make distclean.

[david@tethera.net]

From: David Bremner <bremner@debian.org>

Create a variable DISTCLEAN which contains a list of things to clean
in the distclean target (in addition to running the clean target).

The deleted comment seems to be false these days, since we do create
files during configuration.

Use "rm -rf" here as well in case we want to add directories to DISTCLEAN.
