Details:

(copied from https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=867235)

Attempting to build a program for the new ATmega328PB, it seems the
device-specific IO file is not found:

avr-gcc -std=gnu99 -Wall -Os -DF_CPU=16000000 -mmcu=atmega328pb -flto
-ffunction-sections ...
In file included from src/test.c:1:0:
/usr/lib/avr/include/avr/io.h:623:6: warning: #warning "device type not
defined" [-Wcpp]
 #    warning "device type not defined"
      ^

I do have the required iom328pb.h file though:

-rw-r--r-- 1 root root 27K Jul 22  2016 /usr/lib/avr/include/avr/iom328pb.h

Further, I see that iom328pb.h isn't listed in the big long section of
#ifdef-guarded #includes in the main io.h. I see there is an attempted generic
fallback section based on value of __AVR_DEV_LIB_NAME__ but it seems for
whatever reason that isn't kicking in today.

If I simply add the required 2 lines (by copying the 328P example), my code
will compile fine. Attached is my patch and the new file.
