Adding options -lc -specs=nosys.specs allows arm-none-eabi-gcc v4.9 for compilation

[enthusiasticgeek]

I am wondering if adding options "-lc -specs=nosys.specs" to the build.sh (https://stackoverflow.com/questions/13235748/linker-error-on-a-c-project-using-eclipse) for compiling with arm-none-eabi-gcc v4.9 is considered? It seems to remove all compilation problems with version 4.9 if any.

Thanks @enthusiasticgeek I will fix this soon as I progress the tutorials so RPi3 and RPi3B+ are covered. Then I'll catapault the gcc version forward to a recent version. Thanks for the specs, I think that may be better than what's there right now.

We're using gcc 9.x now, and everything appears to be working well.
