[BBv2] Patch to Darwin (MacOS X) toolset

From: Christopher Currie (Christopher_at_[hidden])
Date: 2003-11-05 23:30:01

This patch is an incremental improvement to the darwin toolset.

* Set the proper suffix for shared libraries
* Added C and C++ compile options used in v1:
-Wno-long-double, -no-cpp-precomp, and -fcoalesce-templates
* Converted the link.dll rule to use the bundled libtool
* Added support for linking to frameworks

This toolset is still in its preliminary stages, so it still needs lots 
of work and testing to get it up to the level of v1. Particularly, Rene 
Rivera commented that it took some time and effort for v1 to work with 
Boost.Python.

I managed to fix my local Jamfile.v2 to get Boost.Python itself to build 
and link, but there isn't a Jamfile.v2 in libs/python/test, so I don't 
know if the library works yet.
