Arnaldo Carvalho de Melo 005cc008bc perf test record+probe_libc_inet_pton: Ask 'nm' for dynamic symbols
Adrian reported that this test fails in his system where:

  probe libc's inet_pton & backtrace it with ping: FAILED!
  root@kbl04:~/git/linux-perf# nm -g /lib/x86_64-linux-gnu/libc-2.19.so | grep inet_pton
  nm: /lib/x86_64-linux-gnu/libc-2.19.so: no symbols

This fails on ubuntu systems, with Adrian's being kubuntu 14.04, I
tested with ubuntu 14.04.4 and 18.04, and there we need to use the
-D/--dynamic 'nm' option to have this test working. And it works as well
with that on fedora 27, so use it.

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.
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.
