fatbuild fixes:
- A change to define CXX in fatbuild, which comforts the configure script a little, even if we don't use C++ anywhere.
- Some code to see how many CPU cores exist and parallelize make across them.
- CFLAGS that apply to both archs are specified seperately (-O3, -pipe, etc)
- -fvisibility=hidden for the gcc4 builds
- a "clean", "clean-ppc" and "clean-x86" command
- Fix to SDL_config_macosx.h for the HAVE_ALLOCA_H thing.
Now builds on an Intel Mac.
