func NeedsGoBuild

func NeedsGoBuild(t Testing)

NeedsGoBuild skips t if the current system can't build programs with “go build” and then run them with os.StartProcess or exec.Command. android, and darwin/arm systems don't have the userspace go build needs to run, and js/wasm doesn't support running subprocesses.

SkipAfterGo1Point skips t if the Go version used to run the test is newer than 1.x.
