I'm not a cross-builder so I'll rely on you all for this.

If this change depends on other things in core-updates I'll leave it,
or if cross-building has had changes on core-updates. If it is just
something that can be done based on current master, I can cherry pick
the change from core-updates and apply this patch on mesa-updates.

What will work for everyone here?

I think my timeline will be quicker but I don't think this is
critical? I was just starting to gather what to apply on the mesa
branch, just waiting for the next mesa release (normally very quick
but current series has been delayed).

Thanks!
John
