Hi! While working on the “reproducible builds” effort [1], we have noticed that some packages failed to build reproducibly because the order of libraries listed in shlibs varies depending on the order of files on the filesystem. The attached patch modifies dh_makeshlibs to sort the files, resulting in a stable order in shlibs files. This allows more packages to build reproducibly.

Subject: [PATCH 1/3] dh_makeshlibs: ensure a stable order in shlibs files
We now sort the list of .so files to have a stable order in shlibs files.
This was preventing some packages to build reproducibly.
