/* This table intercepts weirdo options whose names would interfere

   specs processing without interference.

   Do not expand a linker option to "-Xlinker -<option>", since that
   forfeits the ability to control via spec strings later.  However,
   as a special exception, do this translation with -filelist, because
   otherwise the driver will think there are no input files and quit.
   (The alternative would be to hack the driver to recognize -filelist
   specially, but it's simpler to use the translation table.)

   Note that an option name with a prefix that matches another option
   name, that also takes an argument, needs to be modified so the
   prefix is different, otherwise a '*' after the shorter option will
   match with the longer one.
