Added info about dynamic linking to doc

Browse source 
Added dynamic targets to example makefiles
Added ocaml_dynamic and ocaml_dynamic_cpp targets to Examples/Makefile.in
Added OCAMLFIND and OCAMLDLGEN AC_SUBST lines in configure.in
Currently, dynamic linking relies on ocamlfind and Gerd Stolpmann's Dl package,
as well as some tricky elf linking.

examples and test-suite which come with SWIG. You can do this by running
<tt>make check</tt> from the SWIG root directory after installing SWIG.
The Ocaml module has been tested using the system's dynamic linking (the
usual -lxxx against libxxx.so, but not using the explicit dynamic linking
provided by the Dl package <a
href="http://www.ocaml-programming.de/packages/documentation/dl/"> http://www.ocaml-programming.de/packages/documentation/dl/
</a>, although I suspect that it will work without a problem. If anyone
would like to evaluate this support, I will share the results here.
usual -lxxx against libxxx.so, as well as with Gerd Stolpmann's
<a
href="http://www.ocaml-programming.de/packages/documentation/dl/">Dl package
</a>. The ocaml_dynamic and ocaml_dynamic_cpp targets in the
file Examples/Makefile illustrate how to compile and link SWIG modules that
will be loaded dynamically. This has only been tested on Linux so far.
