When trying to cross-compile a Go program that uses cgo, you need to have a C cross-compiler. In your case you are building with the C native compiler. That can't work.

@ianlancetaylor Yes, I know, I am only confused a little that having cgo only for race detector worked well in all previous Go versions with native compiler (like with 1.11.6)

We had to change the way that the Darwin port works, as mentioned at https://golang.org/doc/go1.12#darwin .
