with the minimum runtime version bumped to 11.0, our current version of pre-compiled clang we use for macOS is too old to understand -mmacosx-version-min=11.0 because it expects =10.x. So I've made the smallest possible bump (from 10.0.1 to 11.1.0) to a version that understands. This bump is arbitrary and unfortunate, but likely to be short-lived as we may end up replacing it with llvm+lld for v26 anyway. I've held off on bumping the SDK as I think that makes sense to do as part of the lld switch instead.
