What's the output look like if you don't have the crt*.o files in
/usr/local/avr/lib/gcc-lib/avr/3.3?

So try this:

  $ cd /usr/local/avr/lib/gcc-lib/avr/3.3/../../../../avr/lib
  $ pwd

and see where you are at. Should be /usr/local/avr/avr/lib and you
should see the crt files there (along with avr[345] dirs) [assuming
that you installed avr-libc using --prefix=/usr/local/avr].

Here's the output on my system:

$ avr-gcc -v -mmcu=atmega8 -o demo.elf demo.o

Hmmm, I see that yours doesn't show a option similar to this:

 -L/home/roth/local/avr/lib/gcc-lib/avr/3.3.1/../../../../avr/lib/avr4
