use native C serial libraries to list ports

since we are already using CGO for most platform, make it compulsory

https://releases.linaro.org/15.06/components/toolchain/binaries/4.8/arm-linux-gnueabihf/gcc-linaro-4.8-2015.06-x86_64_arm-linux-gnueabihf.tar.xz
is used as default arm cross compilation toolchain
