Bug#1100837: clisp: cl-babel's autopkgtest segfaults after latest revision

["Peter Van Eynde" <cl-debian@pvaneynd.mailworks.org>]

Hi,

I cannot reproduce this failure on a real machine:

I can only conclude that the autopkgtest machines don't like running clisp programs.

I'll prepare a new version of cl-babel which removes the testing as it's very minimalist anyway this won't be a big loss.
