This one is a bit obscure. What's happening is that make wants
recipies to have tab characters at the beginning of the lines, and not
spaces. The leading spaces are ignored, so your makefile is being read
is if it looked like this:

program : $(TARGET).hex

avrdude -p $(PART) -c $(PROGRAMMER) -e flash:w:$(TARGET).hex

The colon on this line is being treated as a target/prerequisite
separator. If you put a tab character at the beginning of the line
then it will be treated as a recipie line rather then a dependency
line.
