Ubuntu 安裝arm-linux-gcc編譯器

/**********************************************************************************
 *                      Ubuntu 安裝arm-linux-gcc編譯器
 * 說明：
 *     Ubuntu下直接安裝arm-linux-gcc編譯器，免得去配置那些環境。

1、參考文檔：
    Install the ARM cross compiler toolchain on your Linux Ubuntu PC
        https://www.acmesystems.it/arm9_toolchain

2、查找支持armhf的軟件包名：
    zengjf@zengjf:~/zengjf/zengjfos/busybox/busybox-1.26.2$ sudo apt-cache search arm | grep gcc | grep armhf
    gcc-arm-linux-gnueabihf - GNU C compiler for the armhf architecture
    libgcc-6-dev-armhf-cross - GCC support library (development files)
    libgcc1-armhf-cross - GCC support library
    gcc-multilib-arm-linux-gnueabihf - GNU C compiler for the armhf architecture
    gccgo-arm-linux-gnueabihf - Go compiler (based on GCC) for the armhf architecture
    libgcc-4.7-dev-armhf-cross - GCC support library (development files)
    libgcc-4.9-dev-armhf-cross - GCC support library (development files)
    libgcc-5-dev-armhf-cross - GCC support library (development files)
    libgcc1-dbg-armhf-cross - GCC support library (debug symbols)
    libsfgcc-4.7-dev-armhf-cross - GCC support library (soft float ABI development files)
    libsfgcc-4.9-dev-armhf-cross - GCC support library (soft float ABI development files)
    libsfgcc-5-dev-armhf-cross - GCC support library (soft float ABI development files)
    libsfgcc-6-dev-armhf-cross - GCC support library (soft float ABI development files)
    libsfgcc1-armhf-cross - GCC support library (soft float ABI)
    libsfgcc1-dbg-armhf-cross - GCC support library (debug symbols)

3、安裝命令：
    1. sudo apt-get install gcc-arm-linux-gnueabihf
    2. 安裝結果：
        zengjf@zengjf:~/zengjf/zengjfos/busybox/busybox-1.26.2$ arm
