The problem is that sometimes you have installed two differnt binutils. 
Maybe one come
with system distribution (debian, red hat, suse...) and one with avr tools.

If you now do a compile for simulavrxx it is possible that the system 
header for bfd is taken
and the avr-libfd.a is linked. The result could go from all is working 
to system crash. I had
this problem one time and it was really hard to debug. The reason was 
that a structure
has one more member in it and so the access to the structure was wrong. 
And if you
access wrong memory.... :-)

So: Yes, you must link against the avr-libbfd and must also use the 
header which comes
with your compiled version for avr. It doesn´t really matter if that is 
the same
binutils like for your system, if so you could include also the system 
header, yes. But
there is no waranaty for this.

Thats it
