... from which it should be obvious that this is the wrong, 32-bit blob
"blushes". Patching gives the right, 64-bit blob.

After setting the environment, I can start the server using flatpak run
--devel, but not without --devel. I presume it does something disallowed
in the sandbox, but have no clue to what (I cannot run strace without
--devel).

Any clue how to proceed?  Enclosing a strace log from starting the
server in a --devel sandbox [2]
