Subject: [PATCH] guix: tuned-package: Use target on cross-compile.

From: Jean-Pierre De Jesus DIAZ <[email-masked]>
Date: Wed, 26 Jul 2023 17:37:29 +0200

* guix/transformations.scm (tuned-package): Use either bag-target if
  available or bag-system to select the CPU architecture of the package
  that is going to be tuned.  This enables the tuning of cross-compiled
  packages.
