Shameless self-promotion: I think I hold the record (83 bytes) for the shortest hello-world Linux ELF executable: https://github.com/pts/mininasm/blob/master/demo/hello/hello...

Try 81 bytes for an x86-64 executable, or 77 bytes for the same if you run it on a VM with 5-level paging: https://tmpout.sh/3/22.html
