This patch gets you a start at triggering.  Without the change to ltmain
some failures are silent again; again this patch is obviously not ready
or meant for inclusion the way it is now, just for exposing bugs.  :)
It triggers the "non-existing $export_symbols in case of reloadable
objects" on every system, AFAICS.
(You may have to add more failure-exposing patches.)

And by the way, my last proposed stresstest rework from yesterday errs
wrt. shell quoting and just happens to work by chance.  And is generally
ugly, too.  Oh well..

Cheers,
Ralf
