The ELF note format is sane enough, although it looks like it's not

Hm, I think offset+length would be better: it's how they're represented
in a normal ELF file, so you can just extract the length if you're
extracting the notes. Also, generating a terminating note with the
current linker-based notes machinery would be a bit of a pain.

.notes : {
*(.note.*)
. = ALIGN(4);
LONG(0);
LONG(0);
LONG(0);
}

Am I missing something?
