[OE-core] RFC: external toolchain recipes in OE-Core

[Paul Eggleton]

Hi all,

Currently we have an external-sourcery-toolchain recipe in OE-Core; one of the 
main reasons we have it there is as an example of how to create a working 
external toolchain recipe for those that need to create their own. Since the 
creation of the meta-sourcery layer however, this recipe has been left largely 
unmaintained. Even assuming nobody tries to use it as-is with the CodeSourcery 
toolchain, without testing and maintenance the recipe can bitrot (and has 
broken as a result of changes elsewhere in OE-Core), and thus any external 
toolchain recipe created based upon it may end up not working either. We need 
to come up with a plan for what to do with this recipe - here are some 
possibilities:

A) Keep it in OE-Core and ensure it is tested and maintained

B) Remove it and just point to meta-sourcery as a maintained and working 
example of how to write an external toolchain recipe

C) Replace it with a less concrete example recipe in meta-skeleton that we 
maintain going forward

What do people think?

Cheers,
Paul
