/* This table intercepts weirdo options whose names would interfere
with normal driver conventions, and either translates them into
standardly-named options, or adds a 'Z' so that they can get to
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.
The SUBTARGET_OPTION_TRANSLATE_TABLE macro, which _must_ be defined
