Subject: [PATCH] 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

Patch from Christopher Currie.
