This flag ensures that the tblgen tools do not actually touch the produced .inc file, if there are no changes to the contents. In turn, this may prevent a number of rebuilds of files that include such .inc files, saving build time. While here, ensure that the shell invocations to locate the used tblgen binary do not show unnecessary error messages. Reported by: des MFC after: 1 week
