It's actually doxygen that uses libclang.  Otherwise, that's correct.
(And I think the reason for llvm build-depending on ocaml is that
there's a seldom-used ocaml binding included in the package.  That
might be another place that a build profile, like "stage1" or
"no-ocaml", could potentially break the cycle.  Though at this point
in my bootstrap process there are several other packages that
llvm-toolchain-* is blocked on, so I'm not sure if that would be
sufficient.)

On a second look at this cycle, I guess yet another possible place to
break it would be if libxcb could be updated to build-depend on "check
<!nocheck>".

Thanks.
