I have tried to use the -nostartfiles and -nostdlib option and it does exactly
what you want.

I have tried this command:
/usr/local/cross-tools/bin/avr-gcc -v -x assembler-with-cpp
-nostartfiles   -nostdlib -o test_blink test_blink.asm

And got this output:

If you don't like the -L's and the -D's, you have to call avr-as and avr-ld
directly.
