tools: add mold, a modern linker 

mold is a faster drop-in replacement for existing Unix linkers.

A single binary is able to link various targets, which is why this lives
in tools/.

All toolchain builds then just need to copy the linker over, hence avoiding
multiple builds with the same outcome.
