What's the failure?  
The program directly uses both libpthread and libdl functions.

The bug is probably that this is using LDFLAGS which comes too early to
see the references.  Internal library references should be added to the
dependency list of the target.

Yes, this is the cause of the problem I am seeing. Is there a better
way to fix it than the patch I proposed? I am not familiar enough with
the build infrastructure yet to know what the best way is.

Thanks,
