Problem Description

Hi there, I'm trying to change the behavior of the postmortem_report() call not to print anything to the Serial upon a crash. The serial port in question is connected to a peripherical and is not used for debugging purposes.

So far, my efforts in #9193 have been unsuccessful. I am unable to override the postmortem_report() call via my code.

This got me thinking, can you possibly please introduce a new flag that would prevent the default function from being defined, or avoid printing to the serial? Currently the custom_crash_callback() callback is called after the postmortem_report() has finished printing to the Serial port.

The addition of this would be awesome.

Thank you for the project!

It would be awesome if we could somehow override postmortem_report() completely.
