FS #6705 - ARM optimisations for libmad by Tomasz Malesinski. Modified slightly by me to not put code in IRAM for PP502x (it's slower), and for the mpegplayer version of libmad for PP5002 (there isn't enough room). On my ipod Color, it increases a 320kbps MP3 test file from 169% realtime to 188% realtime. Reported speedup on the ipod 3G was from 118% to 155% realtime for a 192kbps MP3.

Reverted workaround for the gcc warning. There was a change of behaviour in an early development snapshot of gcc 4.1.2, which was reverted later. The workaround triggered the warning it should fix in later gcc 4.1.2 snapshots.

Patch #5219 by Antonius Hellmann. Several optimisations to libmad. Both Coldfire and ARM targets should benefit much from this.

OK, GCC obviously has a hard time with this. Let's just pretend GCC 4.1 doesn't exist for now and revert last change.
