[PATCH] D79400: [CMAKE] Fix build failure when source directory is read only

[Scott Linder via Phabricator via llvm-commits]

Thank you for the explanation; I'm also still lost as to why `.git/logs/HEAD` is referenced at all then. I would propose removing `find_first_existing_vc_file` entirely, as it seems to be completely redundant if there is another mechanism for ensuring the VCS header is up-to-date without triggering gratuitous rebuilds, but I will defer to any of the other reviewers on the `blame` for the scripts.
