Re: [patch] Makefile: can't build modules outside the kernel tree if it was built using O=

sadly, some 3rd party src packages don't quite do the right thing with
their kernel include paths and still depend on the include2/asm symlink
to find the platform header files.
i see your point about include2 being somewhat redundant/legacy, however,
as long as we are creating it, we should have it point to the intended
location instead of being a dead link!
