  92    Do not expand a linker option to "-Xlinker -<option>", since that
  93    forfeits the ability to control via spec strings later.  However,
  94    as a special exception, do this translation with -filelist, because
  95    otherwise the driver will think there are no input files and quit.

  99    Note that an option name with a prefix that matches another option
 100    name, that also takes an argument, needs to be modified so the
