This post is to make libs for armeabi, armeabi-v7a, x86 and mips instruction sets.
But the official tutorial is not clear in Windows platform, and the version is too old. So I just write them down.
To begin with, you should have already installed Cygwin32, and change the path to your own path first!
And, a key point is too add TARGET_SYS=Linux when in Windows platform.
** Notice: It's very hard to build the lib on Cygwin64! So, please remember to install Cygwin32! **
