Hi dear Maintainer,

/usr/share/quilt/quilt.make is a remnant of the 1.0 source format.

There's only an handfull of user left:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1129280

Please drop this line from d/rules.

(by virtue of the '-' it is not absolutely necessary,
 but that would help to remove this item from the todo list)

Greetings

Alexandre
