The minimum version of binutils for kernel build is currently 2.23 and
it doesn't support GFNI.
So, it fails to build the aria-avx512 if the old binutils is used.
aria-avx512 requires GFNI, so it should not be allowed to build if the
old binutils is used.
The AS_AVX512 and AS_GFNI are added to the Kconfig to disable build
aria-avx512 if the old binutils is used.
Fixes: c970d42001 ("crypto: x86/aria - implement aria-avx512")

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.
