The important question to be asking at this point:  

Why are you the only person in the world who has had to do this?

Until you have an answer to that, nothing is really fixed.  The thing
that's different for you than for most people, I guess, is that you
originally built the system WITHOUT_CDDL then removed that option.
That's almost certainly a factor somehow.

Also, the copy of the tool within obj that it should use is not the copy
you manually pointed to with those changes.  When newer build tools are
needed, they exist within /usr/obj/usr/src/tmp/.  So... why doesn't
ctfconvert exist for you in that location after making kernel-toolchain?
