Ah, sorry about that.

So a couple of things:

1) Unless I'm missing something you can share the same TMPDIR between multiple 
build directories to get the same result.
 
2) pseudo is a native package. It shouldn't be rebuilt when changing MACHINE. 
In fact I just verified by creating a different build directory with only 
MACHINE changed in the config, it is not rebuilt.

Well, it's required that bitbake is run from the build directory and when you 
use the setup script as intended that's where BUILDDIR points to. I hadn't 
anticipated that anyone would be changing BUILDDIR to point to anything other 
than the build dir, however I don't really think it's a good idea to support 
that.

Cheers,
Paul
