[clisp-list] ./configure misdirections

[Devon S. M. <lisp-hacker@Jovi.Net>]

Error in ./configure "Please do this" directions,
best fix would be to disable config cache by default,
second best fix would be to amend the "Please do this"
directions to have the user disable the config cache.

... now it works but those final directions above are too comically oxymoronic ...
