libcurl 移植 支持https，openssl NDK (一)

一 、编译环境介绍：（有一部分原因是环境造成编译失败）

系统版本:ubuntu-16.04.3-desktop-amd64 64位（可以使用虚拟机）
NDK版本:Android-ndk-r10b                  （已经测试，使用 Android-ndk-r17b无法通过）
源码版本:openssl-1.1.0f                    https://www.openssl.org/source/ （一个稳定不太旧的版本）
二、编译步骤，设置临时编译环境
1.下载 openssl源码 包，解压
2.在openssl源码目录下增加setenv-android.sh

注：如果环境不一样，请修改脚本中如下几个导出的环境变量为自己的环境变量，需要自己确定工具链版本及api版本

_ANDROID_NDK="android-ndk-r10b"

_ANDROID_EABI="arm-linux-androideabi-4.9"

_ANDROID_API="android-L"

以下是具体内容：（32、64稍有区别）
