Jim,
Looks like GCC Link-Time-Optimization isn't working on Jessie's GCC 4.9.2.
Try re-building with:
cd build
make clean
cmake -DENABLE_LTO=OFF ..
make
and see if that fixes it for you. I get a clean compile on my Docker image.
If that corrects the issue, then we can add the instructions to the Wiki. We
already detect broken LTO support in GCC < 4.9.0, but maybe 4.9.2 is also
broken.....
