That's not looking good at all. Now we have two simple generic compiler
tests that avr-gcc is failing for the atmega1284p. To confirm that it is
avr-gcc asking for a non-existent crt file, and not a path issue, I'd
try the following, which on my older version gives:

$ locate crtm1284 crtatmega1284
/usr/lib/avr/lib/avr5/crtm1284p.o
/usr/lib/avr/lib/avr51/crtm1284p.o

Since tales of wombats digging under the concrete slab in the cowshed,
and bumping around under the house floorboards at night are not entirely
on-topic, I'll save them for an off-list reply.
