No, Is not right.
You haven't specified linker script.

Just run make in the same directory.

here is the results:

lab7:/home/max/prog/test_avr-ld$ make
avr-gcc -g -Wall -O0 -Wa,-anhlmsd=test.lst -mmcu=atmega32 -c test.c
test.c:4: warning: 'data' defined but not used
avr-gcc -g -O0 -Wall -mmcu=atmega32 -Wl,-Tavr5_mega32.x
-Wl,-Map=test.map -o test.elf test.o
avr-objcopy -O binary -R .eeprom -R .fuse -R .lock test.elf test.bin
