[oe] [PATCH] bitbake.conf: Add one recipe identifying OVERRIDE based on recipe type

[Khem Raj]

It adds an override based on type of recipe
e.g. recipes ending with usual suffixes like -native -cross, -sdk
add the same to overrides with out leading '-'
It also add the same override for BBCLASSEXTEND
For normal recipes we add 'target' to overrides

This will give up better control over defining and combining
recipes into using BBCLASSEXTEND and still have finer control
if needed. We wont require to have virtclass-xxx overrides
anymore
