Bug#813018: please multiarchify the library packages

As said before, making the library packages M-A: same and moving the plugin 
directory are two different things.  Having looked at more plugin systems, I 
think the approach I like more is to split the plugins from the library 
packages.  This way the multiarched library packages can be used for 
cross-building, without caring about the plugin installations. On the other 
hand, if third party plugins depend on the plugins shipped in the totem package, 
you need an additional dependency for these third party plugins.
