This patch is currently not mandatory but a prerequisites for the second one.
Folks from ClangBuiltLinux project like the combination of Clang compiler and LLD linker from LLVM project to build their Linux kernels.
Sami Tolvanen <samitolvanen@google.com> has a patch for using LD_IS_LLD (see [1]).
Documentation/process/changes.rst says and uses "binutils" that's why I called it LD_IS_BINUTILS (see [2] and [3]).
The second patch will rename existing LD_VERSION to BINUTILS_VERSION to have a consistent naming convention like:
1. CC_IS_GCC and GCC_VERSION 2. CC_IS_CLANG and CLANG_VERSION 3. LD_IS_BINUTILS and BINUTILS_VERSION
