the following actions are to do:

  libsane-brother2.so         nothing to do, not used
  libsane-brother2.so.1       can stay in /usr/lib64/sane/
  libsane-brother2.so.1.0.7   nothing to do, not used
  libbrcolm2.so               copy to a searched directory
  libbrcolm2.so.1             nothing to do, not used
  libbrcolm2.so.1.0.1         nothing to do, not used
  libbrscandec2.so            copy to a searched directory
  libbrscandec2.so.1          nothing to do, not used
  libbrscandec2.so.1.0.0      nothing to do, not used

but for consistency all will be symlinked to /usr/lib/x86_64-linux-gnu
