Hello,

I'm using Ubuntu focal. After pulling a newer version of qemu and 
locally moving up the 'go' package in the make.sh script, I finally got 
the logs to create rootfiles for aarch64 and armv5tel.

What exact distro are you using? I could not manage do complete a build 
for aarch64 nor armv5tel as I ran into segmentation faults.

Kind reagards

Holger
