Hi Team,
I am willing to add s390x support for CFSSL Binaries.
I have observed that make release command is used to generate the binaries and it requires cgo which in turn requires a working compiler toolchain for the target platform. It uses cbroglie/goreleaser-cgo:1.12.12-musl image. I had raised an issue with cbroglie/goreleaser-cgo where they said that it is not maintained anymore.

Any plans of moving this Dockerfile to cfssl / any other public repo?
Also, I came across this issue #1159. Any updates here?
