You have to use -I/usr/src/linux/include *and* also configure and
build a kernel there to have version.h created plus a couple of other
symlinks.
Be warned that you should run the kernel you've built because of
potential binary incompatibilities in the kernel depending which
options you've compiled in. Kernel-package is your friend.
