NDK Shell for Linux/Cygwin(Windows)

自己简单封装了一下ndk-build
支持：
通过修改build-static-library.mk,可以生成静态库
直接解析Android.mk，支持设置安装目录，支持自动拷贝依赖的静态库
添加了系统检测，同时支持Linux和Cygwin(Windows)环境。
使用方法
和以前一样,只是直接调用脚本名字ndk。
支持原来ndk-build参数，如：ndk clean,ndk -h等。
update note:
解决了Windows下make.exe和Symbian编译环境的冲突
同时支持了Linux和Cygwin(Windows)环境下编译
#!/bin/sh

#Your Android.mk Maybe need to add INSTALL_DIR and MY_STATIC_LIBRARIES.
#Now it just support parse these variables:
#   INSTALL_DIR =>Where you want to install the static library.
#   MY_STATIC_LIBRARIES =>Some dependent static libraries,with the full path or relative path.
#NOTICE:
#1.This shell just support parse MY_STATIC_LIBRARIES like this:
#	MY_STATIC_LIBRARIES = ../libafc.a
#	MY_STATIC_LIBRARIES = ../libutf8.a
#2.If you need to run this shell,you must cd to the RIGHT directory
#You MUST see ./${ANDROID_MK},then this shell will run,otherwise it will exit.
