(FWIW, I already fixed a few mistakes locally)

To elaborate more, what I want to achieve.

Assume we have

	obj-$(OPTION) = bar/

in the Kconfig and let's say bar/ contains

	obj-$(X) += zx.o
	obj-$(Y) += zy.o

What I want is to have something like

	bar-prefix = baz
	prefixed-obj-$(OPTION) = bar/

that results *automatically* _if_ I wrote originally something like

	baz-zx-y := zx.o
	obj-$(X) += baz-zx.o
	baz-zy-y := zy.o
	obj-$(Y) += baz-zy.o

without actually modifying the Makefile in bar/.
