In order to be able to anayze this (and either confirm or refute a
possible libtool bug), I would like to see the './libtool --mode=link'
command that fails, plus all of its output with --debug added as first
argument; further the output of
  ./libtool --tag=TAG --config

with TAG replaced by the tag used for the link.

Thanks,
Ralf
