[oe] RFC: "Virtual" native and sdk recipes

[Richard Purdie]

To further update, I merged what was in OE and my Step A into poky. I
also merged some code rearranging into bitbake. This leaves the
following two commits:

This is the patch to add support to bitbake:

http://git.pokylinux.org/cgit.cgi/poky/commit/?h=experimental-virtualnative&id=7e4d5d677f996a9ca621f3ab6aa22cc7c3ef80d8

(3 files changed, 64 insertions, 12 deletions)

and this then changes some recipes in Poky to use BBCLASSEXTEND:

Cheers,

Richard
