(Cf. also [comment:ticket:11674:27] ff.)
The fix is to flip the order of `-ldl` and `-lkernel`, or append a second
`-ldl` in the linking steps.
This may already be fixed upstream (cf. #10903); if so, this ticket should
be closed. If not, [http://wiki.sagemath.org/days34 the Sage/Singular Days
(SD34)] would be the perfect time to fix it.
According to Hannes, this is now '''fixed in svn revision 14381''', i.e.,
not yet in any stable upstream release, so we should incorporate at least
that patch into some new Singular spkg.
