The terminology can indeed become very confusing. In our setup we use the GNU
terminology for cross compilation.

       build machine
           The machine the package is built on.

       host machine
           The machine the package is built for.

In some tools for dependency analysis we develop (dose3) we also use the terms
"native" and "target". For cross compilation, native would be the build
architecture and target would be the host architecture. By your explanation
above, the terms seem to have the same meaning in OpenEmbedded so we seem to be
talking about the same things. :)
