reason: this patch is created for performance optimization in crc calculation only suitable for openeuler of aarch64 architecture。
you can patch it to the source code of zip software package and install the zip software as usual。
effect: with this patch, the zip software can speed up nearly 20% when running than before。
add openEuler zip package for CRC acceleration optimization,by patching it ,the zip software can accelerate by 20% when executing.
you need the following command to patch it:
'patch -p1 < ../unzip-6.0-crc-builtin.patch '
