cURL is included with Mac OS X, so we don't link to it by default.  It is
dynamically opened at run time.  I've never tried building ogg support.

The easiest way to make universal binaries with dependencies is to link
against a a .dylib that contains both architectures.  For
an example, download the SDL source code and look at the file
build-scripts/fatbuild.sh.  This is what we use to make the universal
libSDL-1.2.0.dylib that is included with ioq3.
