A clue for the libstdc++ problem.

[H . J . Lu]

If you take a look at glibc, we have to do some extra work to make sure
shared libc.so is built right. We cannot use the same method for
building generic shared libraries. You have to do the same for
libstdc++. I don't think there is an easy solution.

Here is a kludge. It is not a correct solution for the libstdc++
problem. But I hope you can get some clues. I will spend some more
time on it today.
