request: additional ISA's

[mcandre]

Hi,

I love Go's inherent portability across architectures. I see that the techknowlogick/xgo images currently support linux/amd64 and linux/arm64. Can we please expand these to include more of the architectures that Go supports? So that CGo users can build our applications for more platforms.

For comparison, Docker Hub's official golang image supports more of these other architectures:

https://hub.docker.com/_/golang

Just to be sure, you do you want to run xgo on different architectures or be able to build for different architectures?

The latter should already be possible as xgo supports the following target arches: 386, amd64, arm-5, arm-6, arm-7, arm64, mips, mipsle, mips64, mips64le, riscv64

If you need to link against native libraries, you need to install them for the relevant arch or cross-compile it yourself during the xgo execution using hooks.

I want to expand the buildx platforms of the Docker images.

Yes, I understand GOARCH and link library requirements.

In fact, am requesting both.

• Docker Hub indicates missing Docker platform ISA's. That presents challenges for Apple Silicon users, for example, who need linux/arm64 images by default.
• xgo is missing the Go platforms freebsd/arm64 and windows/arm64, among others. See go tool dist list for more gaps.
