I understand now better how things are connected. Until some time ago I 
always used qemu-system-xxx, but have failed to understand that the 
qemu-xxx user emulation is only about the cpu. So, starting programs 
with a different coding will fail. The binfmt is the way to solve this 
issue. Now only find a decent explanation how to setup the 
/etc/binfmt.d/register for the aarch64, powerpc and maybe other 
architectures.
At kernel.org there is an explanation, but fairly limited and thus not 
very helpful at this point in time.

I keep on digging.
