Ack.  There is a problem with all <=8K devices (that's what I get for
being lazy and testing everything only on ATmega323 :) - the assembler
resolves rjmp offsets too early, instead of letting the linker do it.
Use "avr-objdump -r" to see the difference between avr4/crtm8.o and
avr5/crtm163.o, for example - the latter has R_AVR_CALL relocs and
they are fine, the former is missing the R_AVR_13_PCREL relocs for
all interrupt vectors.

Many thanks for testing and reporting it - I'll try to fix it and make
a new avr-libc release soon.
