  # $(1): generation type - 'exports' or 'deffile'
  #
  # 'exports' generation involves taking a list of the known exports, passing them to
  # gendef.pl to create a temporary .def file, prepdef-ing this .def file and then
  # passing this along to the import library generation tool to create the .lib.exp.
  # This is invoked for components with knowN interfaces that aren't making use of a .mmp
  # listed .def file
  #
  # 'deffile' generation takes the .def file used in the component build, for components
  # that either require a .def file or where a .def file is used to override default behaviour.
  # The .def file will already have been predef-ed during import library processing, so it's
  # just a matter of running the import library generation tool on the temporary .def file to
  # create the .lib.exp
  #
  # The resultant .lib.exp is then available for use in the final link.
