The old GCC ARM Embedded website on launchpad (https://launchpad.net/gcc-arm-embedded) has been superseeded by the new GNU Arm Embedded one (https://developer.arm.com/open-source/gnu-toolchain/gnu-rm). This also means a change of name from "GCC" to "GNU". Reflect this in the enviroment variables so that the proper term is used henceforth. Signed-off-by: Carles Cufi <carles.cufi@nordicsemi.no>
