making sure minikube is deleted before setup to avoid https://github.com/kubernetes/minikube/issues/4132

Not needed when using Go modules.

The default target (out/minikube) was replaced by "makedeploys",
that would always rebuild the deploy .yaml files from .template

Add helper for "go vet", and don't use the test files variable.

Also return an exit code from golint (why is this not default?)

Currently it is hardcoded to build for any GOOS, but same GOARCH.

Change this to allow building for any combination of: minikube-*-*

See https://goreportcard.com/report/github.com/kubernetes/minikube

Similar to the deb, it just packages the standard binary...

It does not build from source, and not for any distribution.
