Merge #307

307: Use build.rs for conditional compilation r=korken89 a=AfoHT

Extend the current test suite to allow for running tests on newer rustc-versions than current MSRV.

Required by #306 to add special tests for future MSRV.

To exclude an example from the regular non-nightly testing:

```
#![no_main]
#![no_std]

#[cfg(rustc_is_nightly)]
mod example {

    use panic_halt as _;

    #[rtfm::app(device = lm3s6965)]
    const APP: () = {
    <more code>
    }
}
```
