USING "-march=native" WORKS
====================

Editing the "build-armv8.sh" script to read "-march=native" resulted in a working executable.  My Rpi-4 now mines "Yescript" algo at ~66H/s, getting a share once every 24 minutes on average.  Slow, perhaps, but Yescript is a top earner on ZergPool today.

Thanks!       --scryptr
