Ubuntu编译gdb-ARM调试环境

参考Qt可用的gdb编译，以及交叉编译gdbserver，以及配置QtCreator远程调试

**编译脚本 **如下:

#!/bin/bash
echo -e "\033[32m 正在执行步骤一：检查python-dev包 \033[0m"
chkpydev=$(dpkg -l | grep python-dev)
if [ "$chkpydev" == "" ]; then
	sudo apt-get install python-dev --force-yes
fi

gcc -rdynamic -o check check.c -ldl && ./check
checkpy=$?
rm check
rm check.c
