[RFC PATCH 2/2] kbuild: Rename and use BINUTILS_VERSION where needed

[Sedat Dilek]

In the first patch I introduced LD_IS_BINUTILS Kconfig.

To be consistent in naming convention I renamed from LD_VERSION
to BINUTILS_VERSION.

So, we have the double "LD_IS_BINUTILS" and "BINUTILS_VERSION"
like "CC_IS_GCC" and "GCC_VERSION".

For the same reason I renamed the shell script to detect the GNU ld
linker version.

In Documentation/process/changes.rst we use "binutils" and GNU ld
binary is part of it (see [3]).

The patches "init/kconfig: Add LD_VERSION Kconfig" (see [1]) and
"arm64: Kconfig: ptrauth: Add binutils version check to fix mismatch"
(see [2]) added checks for binutils >=2.23.1 whereas binutils
version 2.23 is minimum supported version (see [3]).

I have renamed to BINUTILS_VERSION where needed.
