Cross compile rules update

[Jan, Sebastien]

The reason for (native) DKMS modules build failure using a cross-compiled
kernel is that the kernel build tools embedded in the kernel package (like
fixdep) are not built for ARM but for the host (x86 in my case), and fail
when called by native module building.

Any idea if / how this could be solved?
