Yes, indeed.
It feels like a bit of a hack introduced specifically for that
specific case (but not documented as such).

So, Ajan - I guess that means arguably the CI job should be reworked
to call the different arch builds independently. Then the problem
would go away even without the Defines.$ARCH change.
