go build and go run are very slow on a tiny program I have (cgo invocations in particular). I'd like go to cache the binary so that it only rebuilds when the source is newer. I would use a simple Makefile with a % rule, but the language designers claim that go's build support doesn't need Makefiles.
Is there another alternative I've overlooked? Does the go community prefer another build system, maybe hash-based instead, for caching and reusing build products?
