samples/bpf build its own bpftool boostrap to generate vmlinux.h as well as some BPF objects. This is a redundant step if bpftool has been already built, so update samples/bpf/Makefile such that it accepts a path to bpftool passed via the BPFTOOL variable. The approach is practically the same as tools/testing/selftests/bpf/Makefile uses.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
