No, I do not mean like that.
This is just cosmetic (at least for now).
Kbuild conventionally use both $(obj) and $(src), but
they are the same in most places.
If you see the top of scripts/Makefile.build,
$(src) is the same as $(obj).


I fixed this x86 in commit 1742ed2088.
VDSO Makefiles are copied from arch to arch.
