hi, do you know if it is possible to query features in `target.`cfg()`` in `.cargo/config.toml`?
```
[target.'cfg(all(target_arch = "riscv32"))']
runner = "espflash flash --monitor"
```
works but
```
[target.'cfg(all(target_arch = "riscv32", feature = "println"))']
runner = "espflash flash --monitor"
```
makes my binary run in qemu as if the cfg didn't match
