Rather than providing headers for inclusion which replace any offered by the system nolibc is provided in the form of a header which should be added to the build via the compiler command line. In order to build with nolibc we need to not include the standard C headers, especially not stdio.h where the definitions of stdout, stdin and stderr will actively conflict with nolibc. Add an include guard which suppresses the inclusion of the standard headers when building with nolibc, allowing us to build tests using the nolibc headers. This allows us to avoid open coding of KTAP output for selftests that need to use nolibc in order to test interfaces that are controlled by libc.

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.
