commit 135e080006b9c4a1f9b34f39888816275297d571

    Disable symbols file with older dpkg-dev
    
    dpkg-gensymbols(1) in dpkg-dev versions earlier than 1.15.6 because c++ symbol
    patterns are not understood. This poses a problem for backporters. The correct
    solution would be to backport dpkg-dev as well; however, as a temporary
    stop-gap solution, we just remove the symbols file on those
    systems prior to dpkg-gensymbols(1) doing its work.

+2011-02-27 (CK):
+  As a convenience to backporters, we remove the liblinear1.symbols file on
+  systems with a dpkg version earlier than 1.15.6. However, this should be
+  considered only a temporary measure, until a more satisfactory solution is
