Its not that simple sadly. These patches as they stand don't let us
build anything nativesdk other that uninative. This is because anything
needing crypt now needs to have a specific dependency. We can't really
have glibc depend on libxcrypt either since its glibc.
I think we can unravel this enough to make 2.5/sumo for nativesdk but
not in the target case, its too late to require people to change
recipes for dependencies.
I started work on a patch to make this work for nativesdk using
