    build: Build gnu/packages/*.go in four steps.
    
    This allows guix build --target=i586-pc-gnu from an x86 host.
    
    This is a followup to 1aa7ee52c6c520c2dbbdb06f1381466e9fd96294.
    
    * Makefile.am (first_half): Rename to...
    (first_quart): ...this, and also split into...
    (second_quart): ...this.
    (third_quart, MODULES_PACKAGES3, MODULES_PACKAGE4): New variables.
    (make-packages3-go, make-packages4-go): New targets.
    (make-packages-go): Add them.
