I haven't had a chance to look into this in detail but the cross recipes
have been bothering me for a *long* time. I keep taking chunks of time
and dealing with issues. For example, packaging no longer happens in any
of the cross recipes, thankfully. We can share the gcc sources directory
and so on.

Those changes all open up the possibility of moving them to the native
build directory. The only missing piece left is suffixing the recipe
names with the TARGET_ARCH (like gcc-cross-canadian does, its been proof
of concept'd there).

Cheers,

Richard
