[CM] S7 scheme running on Android in NDK

ccrma and sourceforge copies of s7.

That's the truth!  Sorry you got bitten.  As far as I know, that one
spot is the only unaligned access.  Please let me know of any other
troubles.

By the way, how do you run it in Android?  I had somehow convinced
myself that I needed Java.
