librep/rep-gtk/sawfish install directories

["Kim B. Heino" <b bbbs net>]

librep installs library files to:

  /usr/lib64/rep/0.91.1/x86_64-unknown-linux-gnu

rep-gtk installs to:

  /usr/lib64/rep/x86_64-unknown-linux-gnu

sawfish installs to:

  /usr/lib64/rep/x86_64-unknown-linux-gnu

Is there a reason for having version number 0.91.1 in librep path? How
about dropping x86_64-unknown-linux-gnu too? All of those could be
called /usr/lib64/rep.

Same goes for:

  /usr/lib64/sawfish/1.8.0/x86_64-unknown-linux-gnu
  => /usr/lib64/sawfish

  /usr/share/rep/0.91.1
  => /usr/share/rep

  /usr/share/sawfish/1.8.0
  => /usr/share/sawfish

If you want to have version numbers the common way is to use:
  
  /usr/share/rep-0.91.1
  /usr/share/sawfish-1.8.0
