[ydl-gen] Installing additional kernel modules on YDL5

# ls -la /lib/modules/2.6.22-0.ydl.rc4/source 
lrwxrwxrwx 1 root root 57 Sep 17 12:56 /lib/modules/2.6.22-0.ydl.rc4/source -> /home/owen/ydl5/kernel/BUILD/kernel-2.6.22/linux-2.6.22.0

I get the feeling I didn't create that symlink.  It's guaranteed to
be wrong on any systems not internal to Yellow Dog, I suppose.

"build" is not a symlink, but a real directory.  Passing
--with-linux-kernel-headers=/lib/modules/2.6.22-0.ydl.rc4/build
to the OpenAFS configure process allows configure to finish, just
as if I installed the kernel-source module, built a custom kernel,
and passed that directory to confiugre, but the OpenAFS kernel module
still can't be built - it bombs because linux/config.h does not exist:

env EXTRA_CFLAGS="" make -C /lib/modules/2.6.22-0.ydl.rc4/build M=/usr/src/openafs-1.4.2/src/libafs/MODLOAD-2.6.22-0.ydl.rc4-SP modules
make[5]: Entering directory `/lib/modules/2.6.22-0.ydl.rc4/build'

  WARNING: Symbol version dump /lib/modules/2.6.22-0.ydl.rc4/build/Module.symvers
           is missing; modules will have no dependencies and modversions.

Why does it have to be unintuitive like this?  You'd expect the repo
to have a "kernel-devel" package that installed a working set of
kernel headers in the expected place under /usr/src/kernels.  Well,
*I* would expect that.
