Having trouble with cross-platform builds inside a Docker container on MacOS arm64 (Macbook M2) host OS...

The build is easily replicated by...

git clone https://github.com/jkassis/gas
cd go
go run bin/make.go setup
go run bin/make.go buildx

It uses an Ubuntu image setup for cross platform builds and a build script derived from the xgo project to build for multiple platforms using libraries vendored into the project on the HostOS.

Here's what I get from the docker builds...

I'm concerned and confused by the references to what appear to be SDL1.x headers here.
