commit 35a09fd9c1aeb1023352b8e29c483b2fa6c4e41a

    maint: Build all the 'guix' packages in parallel.
    
    Until now, the 'guix' package shipped in binary tarballs and system
    images would be built sequentially for each system type, one at a time.
    Now all of them can potentially be built in parallel.
    
    * Makefile.am (system_flags): New function.
    (release): Run "guix build guix" before "make binary-tarballs" and
    before "guix system disk-image" to build all the 'guix' packages in
    parallel.
