Here lies probably the root cause: try including the usart_0.asm
file instead.

The following template.asm snippet did work out of the (trunk-) box
(note the additional 0 digits almost everywhere)
-----------
...
; initial baud rate of terminal
.equ BAUD = 9600
.set USART_B_VALUE = (1<<TXEN0) | (1<<RXEN0)

.if WANT_ISR_RX == 1
  .set USART_B_VALUE = (1<<TXEN0) | (1<<RXEN0)| (1<<RXCIE0)
.else
  .set USART_B_VALUE = (1<<TXEN0) | (1<<RXEN0)
.endif
; 8N1 is commonly used
.equ USART_C_VALUE = (3<<UCSZ00)
.include "drivers/usart_0.asm"
..........
-----------------

template.hex:
     [echo] Producing Hexfiles for atmega1284p

BUILD SUCCESSFUL
Total time: 4 seconds

-------------

Without that _0 the wrong usart drivers gets included (dont blame
me for that).
