[PATCH 1/3] build system: remove directories created by tests in "make clean"

[david@tethera.net]

From: David Bremner <bremner@debian.org>

These extra directories cause problems for building on Debian twice in
a row.

In order to remove directories, we need to us "rm -rf" instead of "rm
-r". So now we should be extra careful what we add to the variable CLEAN.
