After re-packaging the OTRE for  Bug 320191 -
  [pde] Exporting an OT plug-in requires to have org.eclipse.objectteams.runtime in the ws:
* Simplify by removing intermediate variable OTRUNTIME_LIBDIR
* Fix regressions in, e.g., OTBuilderTests: when OTRE is served from the projects bin folder,
  a linked folder was inconsistently created 
  (missing in the ws-elementTree - to be checked with JDT/Core team).
