Your PR description should not just be saying what you are doing, by why you are doing it. What policy are you following in these removals?

This one *looks* OK to me in that these are older than the minimum API level of the current LTS NDK, but given that you also submitted https://github.com/llvm/llvm-project/pull/161893 where this is decidedly not the case, it's unclear to me what the underlying process driving these changes is.
