I have committed an additional change to gdb:

    https://github.com/Linutronix/binutils-gdb/tree/minicoredumper-section-note

It will now process all notes in the section, skipping over any it does
not recognize. This is an important change. Not only does it allow other
note types to be added in the future (without breaking gdb), but also
adds support for multiple dumplist notes. This is needed because the
coreinject tool will create additional notes for the injected
data.
