Hi Randy.
I have not yet looked into this (burined in the x86 stuff).
But I will try to find time soonish.
What I have in mind is just to use standard kbuild syntax and
then in the top-level Makefile use the following:
$(Q)$(MAKE) $(build)=Dcoumentation/
This will allow us to use things like:

hostprogs-y := getdelays
And Documentation/Makefile would contain:
obj-y := accounting/
to tell Kbuild to descend into the accounting dir.
We will create a dummy built-in.o but that does not matter.
Could that work out for you?
