Bump!

Please see http://lv2plug.in/pages/filesystem-hierarchy-standard.html

Just keeping the default should be fine:
   $HOME/.lv2:/usr/local/lib/lv2:/usr/lib/lv2

Note that the FHS specifies is "$PREFIX/lib/lv2" (not $LIBDIR/lv2).
LV2-plugins should not be installed in $(DEB_HOST_MULTIARCH) folders.

If I remember correctly "/usr/lib/$(DEB_HOST_MULTIARCH)/lv2" was added
in the past to transition wrongly packaged plugins.

Cheers!
