[Amforth] ATmega328PB - hanging

[Stephen S. <dee...@gm...>]

I did see posts/problems with different implementations of AmForth hanging.

Not sure they are related to my issues, but they do seem similar by
description.

*One additional note:*
*The EEPROM has to be reprogrammed for the 328PB to recover, a power cycle
actually does not work!*

I did load the 644 version from the *eval-pollin* directory to my board and
it works fine, so I know it can be built.  Will try the 328 version later
on my Microchip 328PB board.
