> merged, kudu doesn't support ubuntu 16.04 anymore, and for arm64, because
> of an issue of glibc https://issues.apache.org/jira/browse/KUDU-3131, we have
> to use ubuntu 20.04 now, but there is an error raised:
> kudu/src/kudu/util/sse2neon.h:3228:18: error: 'vld1q_u8_x4' was not declared
> in this scope; did you mean 'vld1q_u8_x2'
> This because gcc version is 9.3.0 for ubuntu 20.04, but seems we only
> declared 'vld1q_u8_x4' for gcc which version is smaller than and equal to
