Tear out all the target-libiberty code unconditionally?  See 
<http://gcc.gnu.org/ml/gcc-patches/2011-05/msg01308.html> and references 
therein; building target libiberty at all is a bug in my view.

See what I said in 
<http://gcc.gnu.org/ml/gcc-patches/2011-05/msg01311.html>.  libstdc++-v3 
does not use target libiberty; it uses one source file from the libiberty 
directory.
