The compilation routine for the kernel has an explicit call to
build version.h, which works fine for most kernels, but the
location of it has recently changes.
commit d183e6f5 [UAPI: Move linux/version.h]
commit 10b63956 [UAPI: Plumb the UAPI Kbuilds into the user
header installation and checking]
moves the file to include/generated/linux/version.h and then to
include/generated/uapi/linux/version.h.
As a result kernel builds of 3.7 or bisection builds of intermediate
kernel commits will fail with:
make[2]: *** No rule to make target `include/linux/version.h'. Stop.
Making the explicit version.h build conditional on the version, or
via a file test would fix the problem, but it introduces some complexity
to the build.
Even without an explicit call to build version.h, it is always produced
by the kernel build, so it can simply be removed.
Note: it isn't clear why the explicit build of version.h was originally
required, but the prep phases of the kernel have changed significantly,
so it should no longer be required.
