Example of how to conditionally include semihosting #111

The book mentions several times

When using real hardware [don't do this]

but makes no mention of how to configure the build so that we can leave the code in, but conditionally compile it in only when we wish to run in an emulator or with a debugger attached. It would be very useful to have an example of how to accomplish this without modifying the code.

There's an example right here, in a round about way. https://rust-embedded.github.io/book/start/panicking.html
