error when running jtreg tests

[Maurizio Cimadamore]

I think the problem is caused by a quirk in my gcc - if I compile 
something with

gcc -ldl foo.cpp

it fails with messages similar to the one I mentioned. To make it work I 
have to do:

gcc foo.cpp -ldl

On the other hand, the gcc version included in the dev toolkit works 
with both variants.
