Android源代码编译脚本

前言

在Android源代码编译过程中经常要source，lunch等一系列命令，这个脚本实现了默认保存编译log，无参可编译，可根据需求使用参数，可以单编，清编 update-api等

    -h, --help
        Display this help message

    -i, --image
        Specify image to be build/re-build (bootimg/sysimg/usrimg/all Default: all)

    -j, --jobs
        Specifies the number of jobs to run simultaneously (Default: CPU core Number)

    -k, --kernel_defconf
        Specify defconf file to be used for compiling Kernel

    -l, --log_file
        Log file to store build logs (Default: build.log)
