NekoVM which I'm packaging at the moment[1][2] does this with the Neko
bytecode.

I looked at the ELF format and it's actually way more difficult than I
imagined to work out if a file has 'stuff' appended to it.  In fact I
don't think it's possible to distinguish this case from normal spare
bytes at the end.  So instead I'll raise this as a bug with NekoVM and
see if they can just use a normal note section.  (Probably not though,
because they're mostly Windows programmers).
