ARM Embedded Linux Course: error building image using bitbake for raspberry pi 3

I am following the ARM Embedded linux course material and in the lab 1 there is an introduction on how to build an image for a raspberry pi 3. I followed the steps in the course and after modifying the files of bblayers.conf and local.conf, I run the command of bitbake rpi-basic-image which gives me an error of do_compile: oe_runmake failed. How to solve this? I have attached the log file, If I need to add more information do let me know. 

I am a beginner in this field so any help would be appreciated.
