Fix if example code isn't woking

[drbh]

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

sudo apt-get install g++-arm-linux-gnueabihf

now you should be able to see the files in the right place with

find /usr -name crt1.o
