Libtool is also specifying the correct -L and -l arguments to link the same
libstdc++, so I'll assume for now that its use of -nostdlib is not the
problem.  Basically, you have a compiler installed that uses a libstdc++
that is not in the default library search path.  This seems like a broken
system configuration to me.  However, you said that this configuration
worked when building other software with the C++ compiler.  So what's
different?  Are these other things you're building with this compiler also
shared libraries?  What is the result of running ldd on them?
