I'm building the latest version of submgr on arm64-based instance.

Faced this issue while building the docker image:

# gerrit.o-ran-sc.org/r/ric-plt/xapp-frame/pkg/xapp
/root/go/pkg/mod/gerrit.o-ran-sc.org/r/ric-plt/xapp-frame.git@v0.9.3/pkg/xapp/xapp.go:42:2: undefined: testing.Init

Here is the code from xapp.go:

// For testing purpose go version 1.13 ->

var _ = func() bool {
testing.Init()
return true
}()

The same issue causes alarm-go build to fail.
 

Can it be commented out (ignored), assuming I'm using go1.12?
