build/source directories

Hi all -
The SUSE kernel module packages allow you to generate RPMs for all
installed kernels with one run of rpmbuild. This involves the use
of one shared source tree at /usr/src/linux and a group of build
trees rooted at /usr/src/linux-obj. The build trees contain the bare
minimum needed for a kernel tree to be considered "configured."
With the current configure script, it's looking in the
- --with-kernel-source directory for a configured kernel when it should
be looking in the directory provided by --with-kernel. When I specify
./configure --with-kernel=/usr/src/linux-obj/x86_64/smp \
--with-kernel-source=/usr/src/linux
it fails, since /usr/src/linux doesn't contain a configured kernel. I
used KERNELBUILD, rather than just switching KERNELINC, because other
tests (like the one for generic_drop_inode being exported) actually
need to look at the full includes for the kernel.
