This rule looks correct.  PowerPC and Microblaze need to be modified
to use it.  It should not be hard to do, give it a try.  Worst case,
your first attempt is wrong and the rest of us fix it up.  :-)

Hint: PowerPC currently puts the .dtb file in a different directory
from the source .dts file.  It doesn't need to do it that way.
arch/powerpc/boot/Makefile will need to be modified.

I will give it a shot.  The only real difference except for the directory 
structures is powerpc and microblaze add padding to the dtb with the -p 1024
command line argument to dtc.  Is the padding needed when the blob are linked 
into vmlinux proper?

You could use a $(DTCFLAGS) variable to pass in arch specific flags.

Maybe, maybe not.  Padding is required to be able to modify the .dtb
data in-place, which is important when adapting data from other
sources into the device tree structure.  However, when it is linked
into the kernel, the adding of additional data /possibly/ can be
deferred until after the tree is either copied or unflattened.
