Fix if example code isn't woking

After following the examples I still was running into compilation errors because of these missing files
`Scrt1.o: and `crti.o`

It seemed I was missing g++ so I had to run the following apt-get

```bash
sudo apt-get install g++-arm-linux-gnueabihf
```
now you should be able to see the files in the right place with

```bash
find /usr -name crt1.o
```
