Back out changelist 13683
There is a problem with the linkage on my machine. Before this changelist the code didn't build on my machine. After it it builds but fails to run due to missing dynamic linkage. And obviously it breaks the jenkins build.
[git-p4: depot-paths = "//depot/gpgpu_sim_research/fermi/distribution/": change = 13684]
