When KASAN support was being added to the Linux kernel, GCC did not yet support all of the KASAN-related compiler options. Thus, the KASAN Makefile had to probe the compiler for supported options. Nowadays, the Linux kernel GCC version requirement is 5.1+, and thus we don't need the probing of the -fasan-shadow-offset parameter: it exists in all 5.1+ GCCs. Simplify the KASAN Makefile to drop CFLAGS_KASAN_MINIMAL. Also add a few more comments and unify the indentation.

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 reStructuredText 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.
