Building the ARM cross-toolchain

The goal of this part is to building an ARM cross-toolchain with binutils gcc newlib and gdb from source. This is needed so we can compile the code that ends up onto the autopilot board. Newlib is a C library intended for use on embedded systems. It is a conglomeration of several library parts, all under free software licenses that make them easily usable on embedded products.
