Build a runner helper on darwin-arm64

Problem to solve

I am trying to build the GitLab runner and helper from source code on an arm64 Macbook. However, the helper image doesn’t support the arm64 build environment. According to the documentation, the command make runner-and-helper-docker-host is a superset of make runner-bin-hostref. If the runner and helper are the same go binary, why is building the helper on arm64 not supported, but the runner is?

error:

gitlab-runner-helper
go: unsupported GOOS/GOARCH pair arm64/arm64

Steps to reproduce

follow instructions on Contribute to GitLab Runner development using an arm64 mac.

Wondering if this is a miss or intentional.
