Comment:
golang in general should support it, but dockers build system seems to be a lot more complex than just `go get`.
There is no specific issue linked, and I think this has always been the case and the initial merge PR was in the old repository so the history if the PR is lost.

You can try it by removing `nocross=yes` and trying to cross compile it `./xbps-src -a aarch64 pkg docker`, but I'm certain that there are going to be some issues that need to be fixed.
