Subject: [bug#71618] [PATCH] guix: gnu-build-system: Add %gnu-build-system-default-modules.
Date: Mon, 17 Jun 2024 21:10:35 +0200

Since there is no exported variable containing the list of default modules,
every place that needs it (in #:modules for example) needs to copy&paste it
and pray it never changes.

This commit provides new variable exposing the default list, allowing
constructs like this:

    #:modules
    `((srfi srfi-34)
      ,@%gnu-build-system-default-modules)

* guix/build-system/gnu.scm (%gnu-build-system-default-modules): New variable.
(define-module)[#:export]: Export it.
