Quentin Monnet 92426820f7 tools: bpftool: exit doc Makefile early if rst2man is not available
If rst2man is not available on the system, running `make doc` from the
bpftool directory fails with an error message. However, it creates empty
manual pages (.8 files in this case). A subsequent call to `make
doc-install` would then succeed and install those empty man pages on the
system.

To prevent this, raise a Makefile error and exit immediately if rst2man
is not available before generating the pages from the rst documentation.

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.
