Alternatively, instead of relying on the toolchain bundled with this repo,
the ARM embedded bare-metal GCC port works great. Download and install it
somewhere appropriate, and run:

This project provides the base/skeleton necessary to develop
applications targeting ARM Cortex-M microcontrollers.
C/C++ applications targeting ARM Cortex-M microcontrollers.
Based on the MCU selected, it automagically compiles the toolchain,
support/peripheral support libraries, startup code, and an empty main()
function. Everything, even the toolchain, is supplied in pure source
form.

* Considerably better documentation (including prerequisites for builds)
* Running purely out of RAM
* OpenOCD-based debugging
* Support for the ARM proprietary compilers.
* Flash image cooking/generation/uploading
I built this framework for my own personal (and professional) needs, and
