Ack! OE already builds a lot of stuff natively -- there's no need to slow
builds done even more by building something natively that one should be able
to presume exists on every reasonable build machine.  I think if a build
machine has gcc, it shouldn't be too much more difficult to expect a working
bash as well, IMO.
