          apt-pkg/deb/deblistparser.cc: Fix bug in architecture wildcard support.

          Previously, linux-any was always matched, because the code simply
          appended linux- to the APT::Architecture value. Now, it does this
          only if the APT::Architecture value does not contain "-".

Michael, does this seem reasonable? Do you think we might be able to backport this to lucid-proposed?
