patch for compcache recipe

Hi,

I have tried compcache from code.google.com on beagleboard rev B5 and 
n800 for a couple of weeks. It seems helping me getting more usable memory.
The patch will add compcache stuff which provides both compcache kernel 
modules and managing tool.
Tested with recent oe repo on my boards, more evaluation on various real 
hardware platforms needed though.
BTW not touched checksum.ini for the tarball yet.

Cheers,

Zhou Ming
