Marco Elver 85f195b12d kasan: test: fix test for new meminstrinsic instrumentation 
The tests for memset/memmove have been failing since they haven't been
instrumented in 69d4c0d321.

Fix the test to recognize when memintrinsics aren't instrumented, and skip
test cases accordingly.  We also need to conditionally pass -fno-builtin
to the test, otherwise the instrumentation pass won't recognize
memintrinsics and end up not instrumenting them either.

Fixes: 69d4c0d321 ("entry, kasan, x86: Disallow overriding mem*() functions")

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.
