Whoops should have replied to this one.

So this does not solve the issue. As it point it includes
<KERNELDIR>/includes .. just you have to compile the kernel directory so
that  "include/asm" symlink in the kernel directory is made.

This creates a symlink to the symlink and that symlnk which is already
in include path -I $(KERNELDIR)/include

What would probably be better is to add a check to see if
<KERNEL_DIR>/include/asm is created. If it's not give the user an error
to compile there kernel source.
