[bug#65041] [PATCH] gnu: clisp: Add threads support on x84_64-linux.

[Sharlatan Hellseher <sharlatanus@gmail.com>]

Guix's build version of CLISP, fails to load bordeaux-threads:

Error while trying to load definition for system bordeaux-threads
      This implementation is unsupported.

This patch adds support for POSIX_THREADS on x86_64-linux
system.

* gnu/packages/lisp.scm (clisp)[arguments]: Add configuration options to
support threads on x86_64-linux system.
