There is build failure issue when old binutils is used. The minimum version of binutils to build kernel is 2.23 but it doesn't support GFNI. But aria-avx, aria-avx2, and aria-avx512 use GFNI. So, the build will be failed when old binutils is used. In order to fix this issue, it checks build environment is using binutils, which don't support GFNI or not. In addition, it also checks AVX512 for aria-avx512. aria-avx and aria-avx2 use GFNI optionally. So, if binutils doesn't support GFNI, it hides GFNI code. But aria-avx512 mandatorily requires GFNI and AVX512. So, if binutils doesn't support GFNI or AVX512, it disallows select to build. In order to check whether the using binutils is supporting GFNI, it adds AS_GFNI.
