Right, I found out the problem. It's because clang-tools-extra's test Makefile uses the temporary filename "lit.tmp" for both its main lit.site.cfg, and for Unit/lit.site.cfg. If these make jobs get run simultaneously, one or the other temp file can unexpectedly disappear.
The following fixes it, similar to what is done in clang's own test Makefile. Hans, are you OK with me checking this in to clang-tools-extra trunk (not sure who owns that), then merging it to the release_37 branch? Then it is at least fixed for the final build.
