Explicitly pass in arch to make when building, mark GH workflow files as config

[sergeichestakov]

Why

We pass in the arch in the publish workflow so we should do it here for consistency.

In addition, we should rerun the build step anytime any of the workflow files change since those can affect the build.

What changed

Explicitly pass in arch to make in the build workflow. Rerun build step when anything under .github/workflows changes

Test plan

Build steps should run and pass
