Actually the MIPS backend does have an UNSPEC 230.  It is one of the
SYMBOL_64_* unspecs.

See http://gcc.gnu.org/ml/gcc-patches/2012-07/msg01069.html for a start of a
patch which would fix this.  It was rejected by Richard S because it is not
trustworthy in some cases which is correct but I could not see a way to fix
that part though.

Also this note only happens with checking enabled.
