Issue Description:

commits 8d3c30e2fa8e0fec705966b9092c0c1c345dec8e and 5f9c82c7516c9d60c4191c5890aeba39fd7b2042 switched libdispatch to cmake.

Unfortunately, this broke incremental builds on the bots.

Every time we do a clean build it passes. subsequent builds fail - example: https://ci.swift.org/job/oss-swift-incremental-RA-linux-ubuntu-16_10/640/console

We figured this out. It was an issue with the Jenkins setup which was clearing part of the incremental build during an incremental build. I believe that this is fixed already. I'll assign it to Mishal since I cant actually change the Jenkins configuration, and he can verify that that has been done.
