Install GCC Arm Embedded tool chain

Download and run the installer from launchpad.net/gcc-arm-embedded. This is the actual toolset (in other words, compiler, linker, etc.). The GCC toolchain should correspond to the latest supported version, as described in MCUXpresso SDK Release Notes Supporting IMXRT1050-EVKB (document MCUXSDKMIMXRT105XRN) .
