Oh, heh. Left over from profiling. Will remove.

Without hardware acceleration, a cryptographically strong
algorithm is too expensive for pauth_computepac.
Even with hardware accel, we are not currently expecting
to link the linux-user binaries to any crypto libraries,
and doing so would generally make the --static build fail.
So choose XXH64
