It's a matter of missed optimizations. We've got tooling in RHEL 8
which checks for native libraries which aren't being optimized. This
was one of the flagged libs throughout all of OpenJDK. While it
probably isn't needed for performance reasons, it's probly also just an
oversight that opt flags didn't get passed properly for this library.
It shouldn't do any harm.

Thanks,
