The way I had been approaching an addition of 64-bit Darwin to GUB was that, 
due to the Xcode restrictions, on non-Apple hardware GUB would compile all 
non-Darwin targets and simply ignore requests for Darwin targets, perhaps with 
a warning. In order to produce a Darwin release, someone would need to install 
GUB on a Mac and run the Darwin build from there. This would mean that Darwin 
binaries might lag behind other architectures until someone with a Mac could 
get around to producing a build.

To my understanding this is no different than an application *providing* GPU 
acceleration capabilities but not requiring it; it does not mean that someone 
without a GPU cannot run the software, just that they are not using features 
irrelevant to their hardware. We would be *providing* the option to build 
Darwin *if* on a Mac, not requiring a Mac for GUB to run.

If this is still too much of an ask then perhaps I am missing some finer point.
