In v8 mode, dh_makeshlibs will run dpkg-gensymbols on all shared libraries it generates shlibs files for. This means that -X can be used to exclude libraries from processing by dpkg-gensymbols. It also means that libraries in unusual locations, where dpkg-gensymbols does not itself normally look will be passed to it, a behavior change which may break some packages. Closes: #557603
