250c8d028d Fix bug when configuring when building OCaml bindings is enabled 
when using Python2.

The output from ``check_output()`` has ``unicode`` type under
Python 2 but type ``str`` under Python 3. This type ended up being
used inside the ``MakeRuleCmd`` class which asserts that it receives
paths of type ``str``. To fix the problem under Python 2 the asserts
have been made weaker by also allowing the paths to be of type
``unicode``.

7cc12bf59f Update information in `README.md` on Python bindings. Since 
e9ea687bb9 they aren't on by default.
Now ``--python`` needs to passed.

Also give better documentation on how install the Python bindings
outside the install prefix.

cb106d71cf Teach the OCaml bindings install rule to respect the DESTDIR makefile 
variable. Previously it would try to install into the system (e.g.
``/usr/lib/ocaml``) regardless of the value of DESTDIR.

Unfortunately it looks like packagers who use DESTDIR to do staged
installs will need to have their packages patch their user's OCaml
``ld.conf`` file manually at package install time (not ``make install``
time) with the extra path to the Z3 Ocaml package directory. We could
use the ``touch`` command to create an empty ``ld.conf`` before running
``ocamlfind install`` but that adds the wrong path to ``ld.conf``
because it contains DESTDIR.

f038291293 Don't silently fail if ocamlfind cannot be found when building the Ocaml 
bindings is enabled. That is really unhelpful behaviour. Instead emit a
warning. I would prefer an error message but apparently being able to
build but not install the OCaml bindings is desirable.

Whilst I'm here also print information about ocamlfind where it should
have been mentioned.
