Since that patch didn't work, here's one I've actually tested, and
that appears to fix the problem for me. Ok to install (in libtool
MLB, and then, in GCC)?
Index: ChangeLog
from Alexandre Oliva <oliva@lsd.ic.unicamp.br>
* ltmain.in (piecewise linking): Make sure we link at least one
object file at a time into a new reloadable object file.
[whole_archive_flag_spec]: Don't link convenience archives
piecewise.
(piecewise archiving): Clear RANLIB except for the last run.
