Investigate https://github.com/cashapp/hermit for tooling

What problem are you facing?

This build submodule attempts to ensure everyone uses a shared set of tools, using Makefiles. https://github.com/cashapp/hermit appears to be purpose built for this.

How could Upbound help solve your problem?

We might consider using https://github.com/cashapp/hermit to simplify our Makefiles.
