[clisp-list] *FEATURES* does not reflect --with-threads.

[Tobias C. R. <tc...@fr...>]

I'd like to request pushing :THREADS onto *FEATURES* if built with
--with-threads. At the moment, you can test for this via 

  (find-package :threads),

I suppose. But it's not as convenient to use in reader conditionals.
