I understand why you want this, however, this will likly break other
packages. This adds the kernel headers to the search path of all packages,
and there will be packages, that cannot be build with newer kernel headers.
Usually because they need old obsolete APIs that got removed in newer
kernel versions.
This is something I have to fix whenever I release a Toolchain with newer
kernel headers. And with the variable version of the kernel headers this
would make things quite difficult to handle.

I think you'll need to patch such packages to accept
-DKERNEL_INCUDE_DIR=/some/path or something like that.
