Bug#633853: [checks/shared-libraries] add information about #204975 to tag descriptions

[Jakub Wilk <jwilk@debian.org>]

Package: lintian
Version: 2.5.1
Severity: wishlist

There's a long-standing bug in debhelper (#204975) that makes lintian 
trigger these tags:

pkg-has-shlibs-control-file-but-no-actual-shared-libs
postinst-has-useless-call-to-ldconfig
postrm-has-useless-call-to-ldconfig

It would be helpful if descriptions of these tags could contain a 
pointer to the bug log.
