Nothing built when disabling TrackFileAccess.

If I do not disable TrackFileAccess in my project file, I get FTK1011 could not create the new file tracking log file: <path>\CL-python-cl_original.read.1.tlog. The file exists. I also get a huge amount of cache misses, and the build takes forever.

If I do disable TrackFileAccess, I get ========== Build: 0 succeeded, 0 failed, # up-to-date, 0 skipped ========== in the logs and nothing built, even though I changed stuff in the files, and clcache is not even invoked.
