[bug-GNUnet] GNUnet test errors on 64-bit Ubuntu 14.04

[ryan]

Test log output attached. I also got an error while running test-driver, 
which doesn't seem to show up on the log at all:

../../test-driver: line 107: 13670 Floating point exception(core dumped) 
"$@" > $log_file 2>&1

Let me know if there's anything additional I can supply to help out.

Thanks,
Ryan
