  MacOS X: Enable 4-way universal builds

  This patch adds a new configure argument on OSX:
          --with-universal-archs=[32-bit|64-bit|all]

  When used with the --enable-universalsdk option this controls which
  CPU architectures are includes in the framework. The default is 32-bit,
  meaning i386 and ppc. The most useful alternative is 'all', which includes
  all 4 CPU architectures supported by MacOS X (i386, ppc, x86_64 and ppc64).

  This includes limited support for the Carbon bindings in 64-bit mode as well,
  limited because (a) I haven't done extensive testing and (b) a large portion
  of the Carbon API's aren't available in 64-bit mode anyway.

  I've also duplicated a feature of Apple's build of python: setting the
  environment variable 'ARCHFLAGS' controls the '-arch' flags used for building
  extensions using distutils.
