Why does ndk/jni building no longer work in 1.8.2?

I don't know what version it stopped working on; I'm developing a new module in 1.8.2. Files placed in the JNI directory do not get built as described in http://developer.appcelerator.com/blog/2011/01/titanium-and-the-android-ndk.html.

I am still testing, but it appears that I can fix it by adding the following code to module/android/build.xml:

<exec executable="${ndk.build}" dir="${jni}">
    <arg line="V=0" />
</exec>

Why was this support removed? Was that intentional? Will it be coming back? I'd rather not have to patch all sdk versions just to use ndk in my module...

Or is there a new method that I haven't found? Perhaps I overlooked something?

Thank you. It's useful.
