Missing ARM image

[mcandre]

Hi,

I often run Go builds on ARM environments, such as macOS and RaspberryPi.

Can we please publish more architecture variants for the xgo Docker images?

As a workaround, I am configuring an environment variable DOCKER_DEFAULT_PLATFORM='linux/amd64' on my Mac, and having to skip creating non-amd64 downstream Docker images for my cgo applications that depend on xgo to build.

For comparison, crazymax's xgo images support ARM:

By the way, I have a tool to help automate the low level docker buildx... commands that manage building cross-architecture Docker images: https://github.com/mcandre/tug
