[PATCH/RFC] zlib: convert to BBCLASSEXTEND

Hi all,

Attached is my first OE patch submission, to convert the zlib recipe to 
use BBCLASSEXTEND and cleanup the do_stage() task.

I would like to start making regular contributions to OE, and am 
starting with the basics. Any guidance from the more experienced folks 
is gratefully accepted.

Scott
