Subject: SDL for Macintosh Programmer's Workshop: removed dynamic loading

I'm working on a game called D2X which uses SDL, and I recently ported
it to Mac OS 9. I used MPW to build it. It uses OpenGL. To get it to
work, I had to build SDL so it doesn't dynamically load OpenGL. This is
because I don't think MPW supports dynamic loading. The following patch
makes sure when SDL is built under MPW, dynamic loading of shared
libraries is disabled.
