The root cause is an error in x/sys which is used by x/crypto/ssh/terminal. The interesting bit is:

/Volumes/opt/go.my/src/golang.org/x/sys/unix/zsyscall_darwin_arm.go:224:23: undefined: SYS___SYSCTL

This was also reported as for #22839 and should be fixed by https://go-review.googlesource.com/79155.

@bonly Can you please check again?

Considering this fixed by https://go-review.googlesource.com/79155

@bonly Please feel free to reopen in case you still experience this problem with the latest version of x/crypto and x/sys.
