Fix request: 21u A prerequisite to backporting JDK-8313643: without this fix, the build with HarfBuzz 8.2.2 fails on Linux. Clean backport. This fix is included into JDK-8313643 backport. Pull request: https://github.com/openjdk/jdk21u/pull/336

I'm backporting JDK-8313643, and the build fails in CI on Linux x64 with exactly the same error. The compilers used in 21u and mainline are the same. Yet the build in mainline doesn't fail even if I revert this fix. It's weird.
