Diff? Maybe the list software has removed the diff. Could you attach it 
as text?

It depends mostly on used distribution. Sometimes (maybe older linux 
distributions) have used it and you have got a linker error, if this 
wasn't available. So, sometimes it's necessary to have it, sometimes 
not. How do you removed it from linking? Editing makefile by hand? Or do 
you have patched ax_avr_environ.m4?

Looks so, that in your simulavr the used bfd lib doesn't recognize the 
elf file. Why? That's a good question. What bfd library is linked in? 
Maybe you have to declare the right bfd lib with the option 
--with-bfd=path in configure. (maybe it works, I know, that there 
sometimes problems with that and then you'll get crashes. So be careful. 
:-) Successful build does not mean, that it really works!)

On my todo list is to replace the bfd library by using ElfIO, because 
it's also a problem on MinGW/Windows. But when ...
