r450: * Modified to use dpkg-architecture instead of dpkg --print-architecture.

     I hate this, and wish it wasn't necessary to make cross compiles for
     the hurd work. Closes: #88494
   * Now depends on debconf-utils for debconf-mergetemplates. Closes: #87321
   * Continues to depend on lynx for html changelog conversions. Yes, these
     and packages with translated debconf templates are rather rare, but
     it makes more sense for debhelper to consistently depend on all utilities
     it uses internally rather than force people to keep their dependancies
     up to date with debhelper internals. If I decide tomorrow that w3m is
     the better program to use to format html changelogs, I can make the
     change and packages don't need to update their build dependancies.
     Closes: #88464, #77743
   * Test for init scripts before running them, since they are conffiles and
     the admin may have removed them for some reason, and policy wants
     us to deal with that gracefully.
   * dh_makeshlibs: now uses objdump, should be more accurate. Closes:
     #88426
   * Wildcards have been supported for a while, Closes: #54197
   * dh_installdocs and dh_link have been able to make doc-dir symlinks for
     a while, Closes: #51225

-There is no guarantee that the program will get the shlibs file right. For
