      hello-go is a simple program printing "Hello, world!" written in Go,
      aiming at testing programs that involves analyzing executables or
      emulating foreign architectures, without pulling in a heavy cross
      toolchain.

      Specify target platform by setting GOOS and GOARCH:

      ```nix
      hello-go.overrideAttrs {
        GOOS = "linux";
        GOARCH = "arm64";
      }
      ```

      See https://pkg.go.dev/internal/platform#pkg-variables for a list
      of available platforms.
