Is libtool used to create this library?  Then this shouldn't happen
(famous last words), and if it does, it's typically the sign of a bug in
the makefiles or in libtool somewhere.

In case libtool is used, please send a message to the bug-libtool at
gnu.org mailing list, including a reference to this thread, and the
output of the `.../libtool --mode=link ...' command that fails, but with
--debug added as first argument to libtool, as well as the output of
  .../libtool --config

Thanks,
Ralf
