[quake3] new osx ppc binary

Ultimately, you have to build with gcc-3.3 on ppc and gcc-4.0 on Intel, 
and use lipo, or you surrender 10.2 and 10.3 compatibility.

It might be broken at the moment, but it should be fixable.

Latest SDL sources in Subversion have a special script for doing a 
universal build on either PPC or x86...historically, I've used lipo on 
that, too.

The OpenAL problems in the Apple system framework? I think the latest OS 
X update squashed several race conditions (Apple committed these fixes 
to their public CVS, too).

We'd ship with a Universal OpenAL included. Not statically, linked, 
though, so people can use the system one if they prefer.

At this point, I'm Ninja Master of universal builds...this should all be 
doable with Quake 3.
