这是一段Makefile语句，用于编译SOM528板卡的多媒体处理程序。具体来说，它执行以下操作：

1. 进入目录$(SOM528_DIR)/mpp/obj并执行make命令，编译默认目标。
2. 进入目录$(SOM528_DIR)/mpp/drv/interdrv并执行make命令，编译所有目标。
3. 进入目录$(SOM528_DIR)/mpp/drv/vendor并执行make命令，编译所有目标。
4. 进入目录$(SOM528_DIR)/mpp/component/pciv并执行make命令，编译所有目标。
5. 进入目录$(SOM528_DIR)/mpp/component/gfbg并执行make命令，编译所有目标。
6. 执行$(MAKE) -C $(SOM528_DIR)/mpp/sample all，编译所有示例程序。

其中，pushd和popd命令用于进入和退出目录，$()用于引用变量。

这是一个 Bash 脚本，用于构建软件包。它包含了两个函数 `build_rpm_package()` 和 `build_deb_package()`，分别用于构建 RPM 和 DEB 类型的软件包。脚本接受一些参数，如架构 `-a`、二进制文件路径 `-b`、操作系统 `-o`、版本号 `-v`、工作目录 `-w`、软件包类型 `-t`、构建 ID `-i`、发布版本号 `-r`、库路径前缀 `-l` 等等。脚本中使用了一些 Linux 命令，如 `mkdir`、`pushd`、`popd`、`rsync`、`sed`、`awk`、`dpkg-shlibdeps`、`dpkg-deb` 等等，用于创建目录、切换工作目录、复制文件、修改文件内容、生成软件包依赖信息等等。脚本最后根据软件包类型调用相应的构建函数，如果类型不是 RPM 或 DEB，则默认同时构建 RPM 和 DEB。

这段输出是在执行 `make` 命令编译 Hi3519DV500 SDK 中的 `boot` 部分时出现的。具体来说，它包括以下信息：

- `configuration written to .config`：指示配置已写入 `.config` 文件。
- `WARNING`：警告信息，提示当前的板子没有使用 Ethernet、Timer 和 Serial 驱动程序的驱动模型。建议在规定的时间段内更新板子以使用驱动模型，否则可能会导致板子被移除。
- `echo "gzip" gzip`：输出提示消息 "gzip" 并执行 gzip 命令。
- `make[2]: *** /home/lkuser/SDK/Hi3519DV500_SDK_V2.0.0.2/mini_sdk/boot/u-boot/../gzip/: No such file or directory. Stop.`：指示在执行 `make` 命令时，出现了错误，因为找不到 `/home/lkuser/SDK/Hi3519DV500_SDK_V2.0.0.2/mini_sdk/boot/u-boot/../gzip/` 目录或文件。
- `make[1]: *** [Makefile:51: all] Error 2`：指示在第一级 `make` 命令中出现了错误，因为在执行 `make` 命令时，出现了错误。
- `make: *** [Makefile:287: boot] Error 2`：指示在执行 `make` 命令时，出现了错误。
