Technically, we only have the x86_64-unknown-linux-none target, but to future-proof ourselves I think it's fine to use a more general cfg.

Theoretically, it's possible that a new linux-none target will be added for a target_arch which is not supported by linux_raw, but I think probability of it is really low and it can be safely ignored.

mod linux_raw;
pub use linux_raw::*;
} else if #[cfg(target_os = "espidf")] {
mod esp_idf;
pub use esp_idf::*;
