Currently a static libdl.a doesn't run all the constructors or 
destructors of the libraries it loads.  I can't see a good reason for 
that, and it does cause aborts in the destructors it does run for things 
like libgcc.so on the Blackfin.

Fixed with the patch below - untested in mainline, but the equivalent 
has been in our Blackfin tree for a while now.
