This reverts commit d641115e20. The goal of this
commit was to make sure that the "guix" specification doesn't fail when there
is no powerpc64le-linux worker around.
The "guix" specification is now only supporting x86_64-linux and i686-linux
while the "guix-other-archs" specification supports powerpc64le-linux and
aarch64-linux.
This will restore powerpc64le-linux system for the "master" specification.

Best practices:
|
||
|
||
1. Store everything in guix-maintenance.git.
|
||
|
||
2. To reconfigure, use the latest Guix available and your personal,
|
||
up-to-date copy of guix-maintenance, e.g. '~/src/guix-maintenance'.
|
||
Use 'sudo' to reconfigure to leave traces.
|
||
|
||
3. Notify guix-sysadmin@gnu.org when reconfiguring.
|
||
|
||
4. Notify guix-sysadmin@gnu.org when something goes wrong.
|
||
|
||
5. Notify ricardo.wurmus@mdc-berlin.de or rekado@elephly.net when the
|
||
machine doesn't respond. Only Ricardo has access to the serial console
|
||
to reset the machine.
