bug#41669: Cross-compiled powerpc64-linux bootstrap-tarballs not reproducible

[Leo Le Bouter]

Hello Chris, Ludo and Efraim,

In my experience, the bootstrap binaries are reproducible on
powerpc64le-linux-gnu for a specific GNU Guix System and GNU Guix
version and configuration. It's not perfect that the kernel version has
to be pinned for reproducibility but it's better than nothing.

The issue with powerpc64le-linux-gnu on GNU Guix core-updates now is
that it has been upgraded to Glibc 2.32 and there is other issues due
to that. Glibc 2.31 is otherwise working well. I wish we could push
changes to build bootstrap binaries to master where there is Glibc 2.31
(and ensure the changes don't affect other architectures) and get this
over with.
