title: How to print a var using echo o print in a NDK-build Android.mk file to debug compilation?
body: <p>I'm trying to print some extra info when in compile a library using ndk-build.</p>
  
  <p>For example:</p>
  
  <pre><code>LOCAL_PATH := $(call my-dir)
  all:;echo $(LOCAL_PATH)
  echo: $(LOCAL_PATH)
  print:echo "i'm not working"
  </code></pre>
  
  <p>When i do ndk-build, just compile all the Android.mk, but i don't get the console echo. I have readed the GNU make info (ndk-build is just a tiny GNU make), and some post whom said echo must work using a $(VAR) but it's not working on my case.</p>
  
  <p>Some idea?</p>
