Relocation error in dce R_X86_64_PLTOFF64 - g++

Question

I've been trying to compile Direct Code Execution (DCE) - an extension to the network simulator ns-3 that can run real programs (VLC, iperf) within the simulator via providing a fake POSIX layer - without success since my upgrade to ubuntu xenial.
To compile DCE, you first run ./waf configure and finally you build the program:
$ LANG=C ./waf build

I admit I've run out of ideas to fix this. It happened first when upgrading my compiler:
gcc version 5.3.1 20160413 (Ubuntu 5.3.1-14ubuntu2)
More info on:
https://github.com/direct-code-execution/ns-3-dce/issues/46
Here is the result of : ./waf build -v
https://transfer.sh/tj7uf/temp
And at https://transfer.sh/qE5Cd/link-step the results of:
LD_DEBUG=all LANG=C /usr/bin/g++ -Wl,--no-as-needed -pthread -pie -lrt -rdynamic test/test-tsearch.cc.50.o -o /home/teto/dce/build/bin_dce/test-tsearch -Wl,-Bstatic -Wl,-Bdynamic -Llib -ltest -lc > link_step 2>&1
(search for R_X86_64_PLTOFF64)
Looking forward to any hint
Cheers
