Guile 2.0 in make-bootstrap.scm

[Ludovic Courtès]

Hi Janneke!

While uploading the powerpc64le-linux tarballs, I noticed they use Guile
2.0, which reminded me of eef44fea17a735d2f4048a747d16af478d4b9dbc:

    Revert "gnu: guile-static-stripped: Update to 2.2."
    
    As discussed on IRC, keeping bootstrap Guile on 2.0 simplifies adding new
    architectures and removes the need for parameterizing
    gnu/packages/bootstrap.scm.
    
    This reverts commit 2acfe022a740f79b593348cc6362cc4ee8f33bb4.
    
    * gnu/packages/make-bootstrap.scm (%guile-static): Revert to guile-2.0.  
Retain
    build recipe.
    * gnu/packages/patches/guile-relocatable.patch: Update for Guile 2.0.14.

Do you remember the reason for this change?

What’s surprising is that
<https://ftp.gnu.org/gnu/guix/bootstrap/i686-linux/20190815> does use
2.2.

Thanks,
Ludo’.
