Note, that test also demonstrates the timer and irq are working :)
Enabling DB_PRINT:
avr_timer16_interrupt: CTC OCRA overflow
avr_timer16_interrupt: interrupt, cnt = 253
avr_timer16_interrupt: CTC OCRA overflow
avr_timer16_interrupt: interrupt, cnt = 269
avr_timer16_interrupt: CTC OCRA overflow
avr_timer16_interrupt: interrupt, cnt = 269
(There is also GPIO accesses but you don't implement them yet).

FWIW we can remove the previous two lines, we don't care about the
baudrate in this test.

Testing shows:
TEST check-qtest-avr: tests/boot-serial-test
qemu-system-avr: Unable to load /tmp/qtest-boot-serial-cOndewD as ELF,
trying again as raw binary
I wonder if this might fail Peter's testing, so Cc'ing Thomas.
