This patch serves no purpose at all (except perhaps on the
gcc-2_95-branch in the GCC repository). libc_interface isn't used
anymore by GCC, and I believe it has never been used by binutils at
all. Moreover, the idea was broken in the first place, see
http://gcc.gnu.org/ml/gcc-patches/2000-12/msg00951.html
Therefore the attached patch seems more appropriate.
