Would you please add a definition of ELF_NOTE_FDO earlier in the file,
similar to ELF_NOTE_GNU?

I would like to point out that the format of the note is JSON-encoded,
so it's not really how we have done things so far in the GNU ABI.  I
guess we can add this as a one-off exception.  It shouldn't be an
example where things are supposed to go in the future.

Thanks,
Florian
