title: configure does not recognize androideabi
body: <p>I am trying to compile a library using android-ndk-r5 standalone toolchain and autotools. When doing a ./configure, it fails with:</p>
  
  <pre>
  $ ./configure --host=arm-linux-androideabi
  ...snip...
  checking host system type... Invalid configuration `arm-linux-androideabi': system `androideabi' not recognized
  configure: error: /bin/sh ./config.sub arm-linux-androideabi failed
  </pre>
  
  <p>Explicitly setting CC and CXX does not work either (configure says to use --host).</p>
  
  <p>The NDK docs and various materials online seems to indicate that using the standalone toolchain in this manner should be possible. What is wrong here? and how can I resolve it? (besides simply ditching autoconf and going back to Android.mk)</p>
