in repository guix.

commit 1aa7ee52c6c520c2dbbdb06f1381466e9fd96294
Author: Ludovic Courtès <ludo@gnu.org>
AuthorDate: Wed Nov 30 17:18:42 2022 +0100

    build: Build gnu/packages/*.go in two passes.
    
    This works around <https://issues.guix.gnu.org/59717>, whereby heap
    usage would go beyond what's reasonable, preventing compilation of the
    'guix' package on armhf-linux.
    
    This is a followup to ef82ba9dd94369926eb13325d5e7da4306d23dd7.
    
    * Makefile.am (MODULES_PACKAGES1, MODULES_PACKAGES): New variables.
    (MODULES_PACKAGES): Define in terms of them and use :=.
    (MODULES_CORE, MODULES_SYSTEM, MODULES_CLI, MODULES_PO): Define with :=.
