Mac OS X Support : Configure and Libs Build system

["Pierre d'Herbemont" <stegefin@free.fr>]

Hi!

This patch add support for Mac OS X's Mach-o in configure.ac and in the 
library. Mach-O differentiate dynamic library that you can link to but 
can't lad dynamically and bundle (shared object) that you can't link 
to, but can load dynamically.
Please tell me if you don't like the way it is done.

Cheers,

Pierre

ChangeLog:
- Add support for Mach-O file format when building libraries
