This is actually correct. If linking librt caused libpthread to also be
linked, then we run into a problem with the use of signals with kernel
oplocks on Linux (see the thread titled "Failed to setup
So in this case, we have to back out out use of librt and therefore
cannot enable clock_gettime. This is really unfortunate, but I don't
think that there's a lot we can do about it.

I think that the patch is doing the right thing. Can you confirm that
librt is linked against libpthread on your system?
