cf. http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=620550

Current version of libqdbm14 (1.8.77-4) has gdbm emulation,
and it will be dropped as,

 1) libqdbm14 -> libqdbm15      (w/o gdbm emulation)
                 libqdbm14-gdbm (w/ gdbm emulation)
 2) libqdbm14 -> libqdbm14      (w/ gdbm emulation)
                 libqdbm15-???  (w/o gdbm emulation)
 3) libqdbm14 -> libqdbm15      (w/o gdbm emulation)
                 libqdbm15-gdbm (w/ gdbm emulation)

According to debian policy 8.1, removing symbols should bump
library ABI version. Which of above (or other) is better way?
