Linking errors for client_fixture and service_fixture tests #52
Description
The service_fixture and client_fixture tests are not linking properly on my machine. The rest work fine.

-ldl is in the linking output, but I think it might be something similar to this issue
I'm on Trusty with gcc version 4.8.4. I think the buildfarm has 4.6.3.
I have seen that the memory_tools tests are doing something specific with dl which might be relevant to these tests as well?
