[PATCH] fix clisp build issues

[Flávio Cruz <flaviocruz@gmail.com>]

Hello

This patches makes it possible for clisp to compile under Hurd using debuild. See "UNIX error" in the log available at https://buildd.debian.org/status/fetch.php?pkg=clisp&arch=hurd-i386&ver=1%3A2.49-10&stamp=1440769077

I'll also submit the patch to the clisp project so that it can also be integrated upstream.

 clisp (1:2.49-10) unstable; urgency=medium
 .
   * Makes clisp compilable under debuild
   * Solves https://lists.debian.org/debian-hurd/2012/06/msg00053.html
