Crude solution, but this way everything else remains "as is",
so once we tackle the issues with the toggle-settings-script not working
in all situations and re-introduce it, we can do easier switch to that
instead.
Fix (partial only) for #105.
Switching to an Arch based build process for easier maintenance and
using specific runners for tasks where that might be necessary.
Right now, parent/child pipelines for somewhat parallel builds for
different architectures / semi-independent pak-builds don't seem to
properly work yet due to `trigger:` not being recognized when it should,
so that's not yet implemented.
