This documentation mentions that rust also needs COMPAT_FREEBSD11 and in fact, rust builds here if I add it to the kernel. I think both are bugs and they need better documentation at least. Neither of them give useful error messages when COMPAT11 is missing. In fact, I was lost in the rust case and solved go case by accident. Not nice.
