in repository guix.

commit f013e88563f73a7513faa330c79eef2f653daf28
Author: Jan (janneke) Nieuwenhuizen <janneke@gnu.org>
AuthorDate: Thu Dec 31 18:25:21 2020 +0100

    commencement: Add stage0-posix.
    
    Stage0-posix is a skeleton for bootstrapping all of Stage0 for POSIX 
systems.
    On x86-linux, from the 357-byte hex0-seed binary from the bootstrap-seeds, 
it
    builds hex0, kaem, hex1, catm, hex2, M0, cc_x86, M1, M2,
    get_machine, (mescc-tools), and M2-Planet.
    
    * gnu/packages/commencement.scm (stage0-posix): New variable.
