The reason of this error output is that the zinc is not supported well on
aarch64, unfortunately, the stand alone zinc is deprecated now, so that we have
no chance to support it on aarch64 in stand alone verison.
Looks like we should skip the zinc related command on aarch64 platform first,
and then upgrade the sbt/zinc in future.
