[CMake] Configure Mac OS X for 32-bit

[Tron Thomas]

Okay, I think I figured it out.  I used this:

set(CMAKE_OSX_ARCHITECTURES "i386 ppc")

At least on my MacBook Pro that sets the architecture to i386 for debug 
builds.  I'll have to try it on the PowerMac to make sure its 
architecture gets set to ppc for debug builds.
