They run in an unpacked source tree as the pwd.  However, this is not
cached across build runs -- instead, the source is freshly unpacked and
made available to the remove target.  So you just need to make sure
that you run the `configure` script if relevant.

There's a special case for `ocamlfind remove` that doesn't do this;
this will likely have to be generalised as OPAM moves the OCaml-specific
logic into a separate plugin.
