This isn't quite true -- either the person compiling uses
the version that is in lib/<platform> (in which case we have
full control of what sdl was configured with), or they can
compile their own version and override stuff with environment
variables to use the output from sdl-config. I am saying
that by default we should should give the blender maintainers
first choice on how blender is linked, and the sdl developers
can have second choice.

In the case of irix, we chose to create a static linking of
sdl into blender so that neither the end user, nor anybody
interested in building blender for themselves need install
sdl if they don't want to (or install any of it's possibly
poorly chosen dependendancies, like aalib).
