-Subject: [PATCH] Assume non-git LLVM is fresh if the stamp file exists
-
-Rustbuild usually writes the LLVM submodule commit in a stamp file, so
-we can avoid rebuilding it unnecessarily. However, for builds from a
-source tarball (non-git), we were assuming a rebuild is always needed.
-This can cause a lot of extra work if any environment like `CFLAGS`
-changed between steps like build and install, which are often separate
-in distro builds.
-
-Now we also write an empty stamp file if the git commit is unknown, and
-its presence is trusted to indicate that no rebuild is needed. An info
-message reports that this is happening, along with the stamp file path
-that can be deleted to force a rebuild anyway.
