Arnaud Vrac f9ab04b63a Add mold linker build
Allows building the #mold linker, which can then be used in the
cross-toolchain by passing the -fuse-ld=mold to the gcc flags. It is
much faster than ld or gold.

This requires a C++20 compiler and cmake.

Initially implemented by Arnaud, and HC added configure check for cmake.

Outstanding task to validate compiler is C++20 compatible.
