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 the MCUXpresso SDK Release Notes Supporting LPCXpresso54018. (document MCUXSDKLPC540XXRN).
