Hi, this happens because we cross-compile the arch:all package (which
we shoudn't) and also bitbake dependencies are not propagated
correctly. Fixing all that has been taken care of in the following
patches:

- handle DPKG_ARCH=all case for transitive deps
- dpkg-raw: add files to source package

These are not yet applied (but hopefully they will be soon).
