To clarify, there are two requirements for being able to use this change:

 1) Naming convention "X" vs. "X-udeb".

 2) There must be a 1:1 between X and its udeb.  For packages that
    "merge" multiple debs into a single udeb, you will also need an
    --add-udeb (combined with multiple -p or even an -a argument).

(The second bit was not explicit in my previous mail).

The covered case therefore matches the pattern:

  dh_makeshlibs -pX --add-udeb=X-udeb ...
