Changes based on the previous Crush patches?

Your patches need to remove the top level changelog entry so that the
version you are building is not foo_1.2.3em1 but foo_1.2.3

What do you get with parsechangelog in a clean tree *before* you try
and build dbus?

Packages already built for Emdebian Crush were never intended to be
build-dependencies for other packages built for Emdebian Crush - Crush
never could build itself, it was always a destination of the build, not
the buildd.

Only Grip can be used to build packages - this is deliberate because
any machine not capable of running Grip is also unlikely to be capable
of running a compiler (let alone installing a cross-compiler as well).

You're only in this situation because no ARM packages exist that have
been built natively. This is therefore a specialised situation and you
need to "undo" some of the changes that result from creating a package
for Crush.

Check the values within the package before you dpkg-cross it - use dpkg
-I libdbus-1-dev_1.2.16-2em1_arm.deb | grep Depends

dpkg-cross would only do this if this was the dependency already in the
package being passed to dpkg-cross.

Then your debian/changelog is probably wrong - in the dbus source
package that you used to create libdbus-1-dev_1.2.16-2em1_arm.deb.
