This improves sane library dependencies, as mandated by debian policy. Some of the librt functions are in such wide use, that we'd get them through transitive dependencies anyway. But linking explicitly against a function adds the DT_NEEDED for this library to our build artefacts. This is correct, since we're actually using these functions ourselves, making them into direct dependencies.
