CRC32 is not a mandatory feature for Armv8.0. What is the arm64 CPU used in your platform?
I'm not sure if it's necessary to use mandatory feature (neon) to optimize hash libraries, because I thought most arm64 CPUs supported CRC32.

The builders we use in Launchpad for package builds are fully virtualized via OpenStack; I checked and we have some older X-gene CPU's which don't have crc32 support.
