Subject: [bug#51838] [PATCH v9 01/41] guix: node-build-system: Add delete-lockfiles phase.

From: Philip McGrath <[email-masked]>
Date: Sat, 8 Jan 2022 03:41:49 -0500

Guix does not use any of these lock files to determine the package versions
used during the build, so they only serve to cause problems.

* guix/build/node-build-system.scm (delete-lockfiles): New variable.
(%standard-phases): Add 'delete-lockfiles' after 'patch-dependencies'.
