Only valid for arm (88f628x) at the moment due to kernel source dependency for drivers.

I hacked in the kernel source (depend) as another cross package which I'm not thrilled about, but no other packages seemed to have a kernel source dependency yet so I wasn't sure where to go with it.
Was hoping that this pull request could open some dialog about how to best implement the kernel source dependencies for all architectures in the future.
