Cannot build on arm64

[chairbender]

Exactly same issue as described in #49 and #48

Looks like there may have been a mistake when applying the fix for this issue. Build.sh is still using || instead of && for the check.

This

if [[ "${MACHINE_TYPE}" != "aarch64" ]] ||  [[ "${MACHINE_TYPE}" != "arm64" ]]; then

Should instead be

if [[ "${MACHINE_TYPE}" != "aarch64" ]] &&  [[ "${MACHINE_TYPE}" != "arm64" ]]; then
