Well, the routine is used to write notes named "CORE" with a note type
that is passed in as parameter (NT_PRPSINFO or NT_PRSTATUS). I think
the only OS on ARM that uses this particular note name/type is Linux.
(OpenBSD for example uses completely different notes ...)
Do you know of any OS that uses a note of the same name and type,
but with different contents?
Interestingly enough, at the same place where I installed the new
routine, routines to *read* those core file notes were already present
Also, the PPC implementation of elf_backend_write_core_note is likewise
installed into the generic PowerPC vector.
