Bpftool determines it's own version based on the kernel
version, which is picked from the linux/version.h header.
It's strange to use the version of the installed kernel
headers, and makes much more sense to use the version
of the actual source tree, where bpftool sources are.
Fix this by building kernelversion target and use
the resulting string as bpftool version.
Example:
before:
$ bpftool version
bpftool v4.14.6
after:
$ bpftool version
bpftool v4.15.0-rc3
$bpftool version --json
{"version":"4.15.0-rc3"}

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
