`./configure --disable-ocaml` does not disable ocaml

Documentation says: " --disable-ocaml disable OCaml language bindings and tools" However ./configure --disable-ocaml && make check results in:

./configure --disable-ocaml --disable-perl && make check is similar I would have expected ocaml and perl tools to not be built and tested. Is this a bug? Can this be explained some other way? Thanks!

`./configure --disable-ocaml` does not disable ocaml #8
