Allow toolchain files to specify an external toolchain. Clang can compile code, but uses the gcc tools for other tasks such as linking. The -gcc-toolchain option can be used for that, but generalize so that other compilers can be treated the same. If such a location is specified, use it as a hint for finding the binutils executables.

CMAKE_<LANG>_COMPILER_EXTERNAL_TOOLCHAIN
----------------------------------------
The external toolchain for cross-compiling, if supported.
Some compiler toolchains do not ship their own auxilliary utilities such as
archivers and linkers. The compiler driver may support a command-line argument
Help: Improve formatting of variable documentation Improve formatting, primarily by: * Adding links to relevant commands, properties, generators, and so on. * Converting code, symbols, paths, and so on to fixed-width fonts. * Hard wrapping lines to 80 characters or less.
