patch by Heliodoro Tammaro <helio at interactives dot org>

- configures/builds on all darwin versions
- ffserver builds on darwin (if you have the extra libraries)
- builds correctly (again) on non-darwin ppc (no -faltivec in gcc-3.2)

Originally committed as revision 880 to svn://svn.ffmpeg.org/ffmpeg/trunk
