<Noah[m]> "Is there a way to define a..." <- I don't *think* so, runner cfg is per target or per cfg according to the docs:

```toml
[target.<triple>]
linker = "…"              # linker to use
runner = "…"              # wrapper to run executables
rustflags = ["…", "…"]    # custom flags for `rustc`
rustdocflags = ["…", "…"] # custom flags for `rustdoc`

[target.<cfg>]
runner = "…"            # wrapper to run executables
rustflags = ["…", "…"]  # custom flags for `rustc`
```
