Dependency on git binary

[andrewbaxter]

Is your feature request related to a problem? Please describe. I'm doing builds in nix and the build environment doesn't have git by default, and I think the git directories too (it might be using an archive tarball). The build fails as is.

Describe the solution you'd like I wouldn't expect this to need git for anything (and I'd like to avoid leaking build environment metadata) - could this be made opt-in?

Describe alternatives you've considered I worked around for now it by setting env var GIT_HASH=fakehash during the build.

You are right. We should check if git is available and gracefully handle the situation in which it is not.

By the way, I'm not sure if I said it before but this is a really cool project! Thanks for working on it. (no rush here, this is more of a convenience thing)

Thank you for your kind words. I appreciate it!
