Sorry, my mistake. It turned out that librt was implicitly linked in
in the 4.9.1 case. However, the only things I use from librt are high
precision timers, so a switch to ensure no performance hit in my own
code would be great.

timers were moved out of librt exactly for this reason. I believe Fedora20 should have a recent enough glibc that you don't need -lrt.
