Subject: [PATCH 1/3] gnu: ecl: Do not compile the deprecated MIT-RT.

From: Guillaume Le Vaillant <[email-masked]>
Date: Thu, 3 Oct 2019 11:01:11 +0200

Compiling the rt bundled with ECL prevents the ecl-rt package from compiling
properly, as ECL thinks it has already been compiled.

* gnu/packages/lisp.scm (ecl)[arguments]: Add '--without-rt' to
  'configure-flags'.
