Explicitly include stddef.h when building the BTI tests so that we have
a definition of NULL, with at least some toolchains this is not done
implicitly by anything else:
test.c: In function ‘start’:
test.c:214:25: error: ‘NULL’ undeclared (first use in this function)
214 | sigaction(SIGILL, &sa, NULL);
| ^~~~
test.c:20:1: note: ‘NULL’ is defined in header ‘<stddef.h>’; did you forget to ‘#include <stddef.h>’?

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.
