Do you have an idea how we can identify whether the installed
ctfconvert(1) is broken or not? I think in Jeremy's case we cannot rely
on OSRELDATE given that right before he built and installed world with
WITHOUT_CDDL, so ctfconvert and OSRELDATE are not in sync.
Why not just always add ctfconvert to bootstrap tools when it is needed?
I don't know how long it takes to build though, but it is probably
nothing compared to LLVM ;-).
