[PATCH] restore previous KERNELDIR behavior

[Muli Ben-Yehuda <muli-7z/5BgaJwgfQT0dZR+AlfA@public.gmane.org>]

My patch to fix the --kerneldir option to configure caused a subtle
change in behavior when --kerneldir wasn't specified. Previously,
kernel/Makefile would set KERNELDIR to /lib/modules/xxx. The fix
caused it to be set to $(readlink -f /lib/modules/xxx) (via
config.mak). Normally this wouldn't have made any difference, a
symlink and what it points to are synonymous, but various places rely
on KERNELDIR being of the form /lib/modules/xxx for pattern
substitution. Switch back to the old behavior.

This should fix the issue reported by Omar Khan <okhan-e94Sedi4moU@public.gmane.org> and
Pelle <Pelle-5JapdU7xTciEVqv0pETR8A@public.gmane.org>
