Did you patch the sources?  The way I've done it is to copy the WinAVR patches 
from the SourceForge site, and throw away any starting with 00- and 10-.  It 
appears from your output that you may have a filename problem, which suggests 
that you compiled gcc with all the patches, including the Win32-specific ones 
that change '/' into '\'.

I use gentoo, and here are my personal instructions for building the AVR 
toolchain:

export PREFIX=/usr/local/avr

binutils

download winavr patches to patches subdir, then
go to binutils root dir (where configure script is)
for i in ../patches/*; do patch -p0 < "$i"; done
(don't use windows patches, which are [01]*)

mkdir obj-avr
cd obj-avr
../configure --prefix=$PREFIX --target=avr --disable-nls
make
make install

gcc
same patch procedure
mkdir obj-avr
cd obj-avr
../configure --prefix=$PREFIX --target=avr --enable-languages=c,c++ \
    --disable-nls --disable-libssp --with-dwarf2
make
make install

avr-libc
no obj-avr, just make in root directory
./configure --prefix=$PREFIX --build=`./config.guess` --host=avr
make
make install (make sure PATH includes avr/bin)

GDB
mkdir obj-avr
cd obj-avr
../configure --prefix=$PREFIX --target=avr
make && make install

avrdude
../configure --prefix=$PREFIX
usual make/install

avarice
mkdir obj-avr
cd obj-avr
../configure --prefix=$PREFIX
make
make install
