eBPF selftests include a script to check that bpftool builds correctly with different command lines. Let's add one build for bpftool's documentation so as to detect errors or warning reported by rst2man when compiling the man pages. Also add a build to the selftests Makefile to make sure we build bpftool documentation along with bpftool when building the selftests. This also builds and checks warnings for the man page for eBPF helpers, which is built along bpftool's documentation. This change adds rst2man as a dependency for selftests (it comes with Python's "docutils"). v2: - Use "--exit-status=1" option for rst2man instead of counting lines from stderr. - Also build bpftool as part as the selftests build (and not only when the tests are actually run).

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.
