How to get libreadline for Android?

http://stackoverflow.com/questions/17697779/how-to-get-libreadline-for-android

I found myself also needing to compile libreadline for arm-linux-androideabi. What I did was the following:

1. download source code for libreadline gnu.
2. set CC to the android-ndk cross compiler (CC=~/android/lib/bin/arm-linux-androideabi-gcc)

3. update the config.sub and config.guess files (the ones in the libreadline source are very old and don't have arm-linux-androideabi)

   $ cp /usr/share/misc/config.{sub,guess} support/.

4. run ./configure with --host and --prefix set to the target architecture and the locations for the compiled objects

   $ CC=~/android/lib/bin/arm-linux-androideabi-gcc ./configure --build=arm-linux-androideabi --prefix=~/android/lib/

5. make && make install and it worked for me! I have libreadline.a and libreadline.so files in ~/android/lib/lib

Note, before I had updated the support/config.sub and support/config.guess files I was getting the same error described in the question.
