Build wireless-tools in Android

Busybox下沒有iwconfig等cmd，只能動手編了

LOCAL_STATIC_LIBRARIES 
    These are the static libraries that you want to include in your module. Mostly, we use shared libraries, but there are a couple of places, like executables in sbin and host executables where we use static libraries instead.

LOCAL_WHOLE_STATIC_LIBRARIES
    These are the static libraries that you want to include in your module without allowing the linker to remove dead code from them. This is mostly useful if you want to add a static library to a shared library and have the static library's content exposed from the shared library.
