falcon-agent arm架构 执行程序生成

1. 安装 golang [1.4+]
   yum install golang
2. 下载 falcon 文件，以及相关部署 GOPATH是go语言运行的环境,go 命令时的程序路径就是此路径
   export GOPATH=/root/go
   mkdir -p $GOPATH/src/github.com/open-falcon
   cd $GOPATH/src/github.com/open-falcon
   git clone https://github.com/open-falcon/falcon-plus.git
   cd falcon-plus/modules/agent
   go get
3. 编译
   部署交叉编译工具链 [arm-2013.11]
   arm-linux-gnueabi-gcc -v

[CentOS]安装软件：/lib/ld-linux.so.2: bad ELF interpreter 解决
bash: /usr/local/bin/rar: /lib/ld-linux.so.2: bad ELF interpreter: No such file or directory
解决办法：yum install glibc.i686

CGO_ENABLED=1 GOOS=linux GOARCH=arm CC=arm-linux-gnueabi-gcc go build

4. 打包 falcon-agent
   打包 agent,cfg.json 两个文件

5. 运行 falcon-agent
   修改 cfg.json hostname:必须唯一

}

./agent -c cfg.json
	可能缺少 arm-linux-gnueabi-gcc 环境的链接文件 ld-linux.so，以及相关依赖库
