@benlangmuir thanks for pointing this out, we should definitely keep that in mind when relanding. We'll try to run the bootstrap process to fix that too.

Are the particular steps for the bootstraping you do documented somewhere? E.g. maybe we're lucky and one of the files in https://github.com/llvm/llvm-project/tree/main/clang/cmake/caches can be used for that?
