Inability to build FreeBSD-current amd64

So now I wonder why I failed four times straight building current.  One definition of insanity is doing the same thing repeatedly and expecting a different result.

Maybe the build host, 11.1-STABLE from July 30, 2017, was too old?  I wouldn't have thought it was too old.

I could also try an old current host from August 2, 2017, or try to build 12-STABLE from my 11.1-STABLE host.  Would I do better to build amd64 or i386 from amd64 host?  I presently have no FreeBSD i386 installation, only amd64.
