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

[Frans Meulenbroeks]

2010/10/22 Khem Raj <raj.khem at gmail.com>:
> 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

Cool. I felt we need -target for quite a while, but could not add it myself.

Next question/proposal:
A big patch to replace things like virtclass-natve to -native ?
And then a patch to remove that functionality ?

Seems liek the way forward.
