Description of problem: building standalone kernel modules outside of the kernel
source tree no longer works under the latest kernel errata   

Version-Release number of selected component (if applicable):

      kernel-2.6.12-1.1372_FC3

How reproducible: always (100%)


Steps to Reproduce:
I have a custom kernel module, which I have successfully build on earlier
kernels by doing a

        export KERNEL_VERSION="the kernel version"
        make

The makefile itself has pretty standard stuff:


        KDIR  := /lib/modules/$(KERNEL_VERSION)/build
        PWD   := $(shell pwd)

followed by target definitions.

In all earlier installed kernels, /lib/modules/$(KERNEL_VERSION)/build was a
directory.

in the latest errata, /lib/modules/2.6.12-1.1372_FC3/build is a soft link to

        ../../../usr/src/kernels/2.6.12-1.1372_FC3-i686

My question is:

        is this a bug ? or is this the way of future kernel module builds ?

and

        given this soft link, do we now have to d/l the rource, and
        install it to /usr/src/kernels/2.6.12-1.1372_FC3-i686 ?

I'm guessing that I would need to do a rpmbuild -bp first.


Actual results:

build fails

Expected results:

a built kernel module.
