Please send the output of
  ./libtool --config

and of the failing 'libtool --mode=link' command, with --debug added as
first argument to libtool.  Send each for both the working and the
broken Libtool version.  You can pack large outputs with gzip.

Which GCC version do you have installed?  Did it change between the
tests?  Is the libstdc++.la file installed, and does libtool find it
(I'll be able to answer this last question by looking at the --debug
output)?

Thanks,
Ralf
