* config/xtensa/uclinux.opt (elf2flt, elf2flt=): Mark as Undocumented.
* config/xtensa/xtensa.opt (mlra): Likewise.
* doc/invoke.texi (Option Summary) <Xtensa Options>: Remove
redundant negative forms plus obsolete -mfused-madd option.
(Xtensa Options): Likewise undocument -mfused-madd. List
negative form of -mforce-no-pic.
