This is a known binutils bug: "avr-ld --oformat ihex" gives bad
output files.  Building an ELF binary, and then using avr-objcopy
to convert it to ihex/srec/whatever works fine, and that's what
the sample Makefiles generally do, so it has been tested a lot...

The problem is wrong masks in bfd/elf32-avr.c (elf_avr_howto_table).
Someone with more time and knowledge of binutils internals should
look into it - for now, use avr-objcopy and all should be well.
Perhaps the --oformat bug should be documented somewhere?

Hope this helps,
