--- Comment #12 from joseph at codesourcery dot com <joseph at codesourcery dot com> 2011-03-02 16:50:20 UTC --- I do not believe any component of the GCC or src tree uses a target libiberty. Thus, I do not think such a target libiberty should be built or installed by default. I also think host libiberty should not be installed by default, but that's a separate matter. http://gcc.gnu.org/ml/gcc/2010-03/msg00012.html http://gcc.gnu.org/ml/gcc-patches/2010-12/msg01231.html
