My first guess is the toolchain or cross compiler is not the one TI uses for development and testing. A toolchain from Linaro is used. That can be downloaded from here.

I also recommend using the TI 7.0 SDK which is based on the 3.12 kernel. The 3.14 kernel while available in mainline is not supported by TI yet.
