I should note that when we take this, it will break existing build
directories due to the way autotools handles external builds. I can't
find a good way to avoid this, hence waiting until I'd done a complete
pass over the OE-Core tree before sending it out.

I have tested world builds with this patch applied and either disabled
out of tree builds for broken recipes, or where possible fixed things
up.

Cheers,

Richard
