Jiri Olsa fdb071f866 perf tools: Do not display extra info when there is nothing to build
Even with fully built tree, we still display extra output when make is
invoked, like:

  $ make
    BUILD:   Doing 'make -j8' parallel build
    DESCEND  plugins
  make[3]: Nothing to be done for 'plugins/libtraceevent-dynamic-list'.

Changing the make descend directly to plugins directory, which quiets
those messages down.

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.
