what
When cross-compiling, ARM builds especially are very slow due to virtualisation during the build process.
This change makes the builder stage in the Dockerfile run in the host os and instead cross compile to the target architecture.
why
After this change, the atlantis-image Workflow in my fork went from running in 12 minutes to 4 minutes, so a third of the time it previously took.
