I'm a bit confused. @kongy Mentioned Glibc 2.27 in their original comment, but then 2.17 in a subsequent comment. The patch itself checks for 2.27. @kongy Can you confirm that you meant 2.27 in https://github.com/llvm/llvm-project/pull/121893#issuecomment-2574965134?

Assuming that's correct, then I think we should actually support this since we do claim to support glibc >= 2.24, and 2.27 is certainly more recent than 2.24. We'd then add this and remove it once we bump the glibc requirement.
