I measured the linking times by running `cargo rustc --bin trinitrix --
-Z time-passes`, which resulted in following data:
`ld`:
37.794s to link
`mold`:
21.389s to link
The downside for now is, that this requires to have mold installed to
build trinitrix (The nix flake based direnv already has it) and that
mold only works on linux.
