This seems to be a bug of binutils 2.19 version. I found a hint in:
http://sourceware.org/ml/binutils/2008-07/msg00129.html

The thing seems to be that libbfd needs zlib but is not linked in from
binutils which is a bug in binutils!!!

As this is a bug in binutils I will not apply changes to simulavr. But
this is a "temporary" patch for the Makefile:
