It appears your problem is that the directory with libstdc++ in it also
has an old MPFR version in it, so passing a -L option for it interferes
with finding the right MPFR. In that case,
--with-host-libstdc++=/usr/lib/libstdc++.so should work - you need to name
the actual file to use for linking libstdc++ rather than giving -L and -l
options.
