參考資訊：
1. unity-car-tutorials

步驟如下：
1. 手動掛載SWAP 2GB
2. 編譯安裝coreutils(/usr/bin/install記得symlink到/usr/local/bin/install)
3. 執行如下命令

$ export GCC_VERSION="4.8.2"
$ export WORKDIR="/home/nemo/Downloads/gcc-${GCC_VERSION}"
$ export INSTALLDIR="/opt/gcc-${GCC_VERSION}"

$ rm -rf ${WORKDIR}
$ mkdir -p ${WORKDIR}

$ cd $WORKDIR
$ wget http://www.netgull.com/gcc/releases/gcc-${GCC_VERSION}/gcc-${GCC_VERSION}.tar.bz2
$ tar -xf gcc-${GCC_VERSION}.tar.bz2

$ cd gcc-${GCC_VERSION}
$ ./contrib/download_prerequisites
 
$ cd ..
$ mkdir gcc-build
$ cd gcc-build
 
$ ../gcc-${GCC_VERSION}/configure --prefix=${INSTALLDIR} --enable-shared --enable-threads=posix --enable-__cxa_atexit --enable-clocale=gnu --enable-languages=c,c++ --disable-multilib --with-arch=armv7-a --with-float=hard --with-fpu=vfpv3-d16
