Should there really be the line:

gcrt0.o: crt0.S

?

The rules seem a little strange, though I'm a bit too toasty at the moment
to hunt down what should be happening.  Bottom line, a make fails on it.

( Specifically, cc -c -DMCRT0 crt0.S is called, followed by ld -x -r gcrt0.o
 when no binary gcrt0.o has been made.  Should there just be a -o gcrt0.o on
 the ${COMPILE.S} line?)
