Thanks for the updates!

>If the core developers say various cross-compiling scenarios aren't supported build configuration any more, I'll accept that and work around the limitation on my end. However, do note there is a significant possibility that Apple stops selling Intel machines for various product models in a few weeks. I suspect various people will want to continue their practice of building x86_64 only binaries for the indefinite future.

I think you make very good points. I also think that we all agree that we do need to work towards better supporting the coming primarily non-Intel Mac world. I would rather put it that there are cross-compiling scenarios that were never supported before (but also not necessarily fully documented as such) but may have worked coincidentally some of the time; moving forward, we need to identify the important scenarios and make sure we fully support them. We're not there yet but I have some ideas on how to do that which I will try to get written down soon.
