sync-with-kernel is a few fragments of shell that live in various parts
of the tree (Makefiles). It's just static shell, the build system doesn't
need to do any substitions.

I think sync-with-kernel doesn't really belong in the build system; This
can be moved into its own shell script.

Nice! This will really help when I'm testing on the rpi.
