You might argue that it's a flaw with the `go build` command, but replace go with cargo/dotnet/maven and you have the same problem.

This is pretty easy in Make, especially since GOOS and GOARCH are environment variables. One way to do it could look like this:

    export GOOS ?= darwin
    export GOARCH ?= arm64 
    VERSION ?= 0.0.0+$(shell git describe --dirty --always)

    build:
        $(if $(VERSION),,$(error VERSION was not set))
        go build -ldflags="-X 'main.Version=v$(VERSION)'"

you could run it as:

    $ make build (uses darwin/arm64/0.0.0+<git ref>)
    $ make build GOOS=linux VERSION=1.0.0 (uses linux/arm64/1.0.0)
    $ GOOS=templeos GOARCH=sparc make build VERSION=1.1.0 (uses templeos/sparc/1.1.0)
