In commitb0438861ef("host-utils: Avoid using __builtin_subcll on buggy versions of Apple Clang") we added a workaround for a bug in Apple Clang 14 where its __builtin_subcll() implementation was wrong. This bug was only present in Apple Clang 14, not in upstream clang, and is not present in Apple Clang versions 15 and newer. Since commit4e035201we have required at least Apple Clang 15, so we no longer build with the buggy versions. We can therefore drop the workaround. This is effectively a revert ofb0438861ef. This should not be backported to stable branches, which may still need to support Apple Clang 14.
