Makefile bugfix
Ben Avison authored
Detail:
  ModuleLibs used the wrong (non-zM) version of RISC_OSLib. This meant that
  any module using the shared makefiles and RISC_OSLib ended up using the
  static initialisers instead of static data, meaning that it could not be
  reinitialised or multiply instantiated. This was rather critical for the
  FrontEnd module, which relies on being reinstantiated for each new tool.
Admin:
  Fixes the reported bug in FrontEnd 1.31 - verified it now works with more
  than one tool loaded.

Version 5.14. Tagged as 'BuildSys-5_14'
