Daniel Bristot de Oliveira c7d8a598c5 rtla: Fix Makefile when called from -C tools/ 
Sedat Dilek reported an error on rtla Makefile when running:

    $ make -C tools/ clean
    [...]
    make[2]: Entering directory
    '/home/dileks/src/linux-kernel/git/tools/tracing/rtla'
    [...]
    '/home/dileks/src/linux-kernel/git/Documentation/tools/rtla'
    /bin/sh: 1: test: rtla-make[2]:: unexpected operator    <------ The problem
    rm: cannot remove '/home/dileks/src/linux-kernel/git': Is a directory
    make[2]: *** [Makefile:120: clean] Error 1
    make[2]: Leaving directory

This occurred because the rtla calls kernel's Makefile to get the
version in silence mode, e.g.,

    $ make -sC ../../.. kernelversion
    5.19.0-rc4

But the -s is being ignored when rtla's makefile is called indirectly,
so the output looks like this:

    $ make -C ../../.. kernelversion
    make: Entering directory '/root/linux'
    5.19.0-rc4
    make: Leaving directory '/root/linux'

Using 'grep -v make' avoids this problem, e.g.,

    $ make -C ../../.. kernelversion | grep -v make
    5.19.0-rc4

Thus, add | grep -v make.

README 

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.
