It is useful to be able to build single object files, e.g.:
$ make net/sched/cls_flower.o W=1 C=2
Currently kbuild does a hard include of a Kbuild or Makefile
for directory where that object would reside. Kbuild doesn't
cater too well to multi-directory drivers, meaning such drivers
will usually only use a single central Makefile. This in turn
means it will be impossible to build most of object files
individually for such drivers.
Make the include of $dir/{Makefile,Kbuild} optional.

I must admit I have no idea whose tree I should send this to :(
Could it go via net-next if no one on linux-kbuild objects?
