ERROR: libfaac not found while compiling FFMPEG library

Question

I was trying to compile FFMPEG library under ubuntu for android with including all possible codecs. i followed this tutorial http://www.roman10.net/2013/08/18/how-to-build-ffmpeg-with-ndk-r9/. but when i execute ./build_android.sh it gives me this Error:

root@AK-74:/home/rango/Desktop/android-ndk-r10e/sources/ffmpeg-3.0# ./build_android.sh ERROR: libfaac not found

If you think configure made a mistake, make sure you are using the latest version from Git. If the latest version fails, report the problem to the ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net. Include the log file "config.log" produced by configure as this will help solve the problem.

Here is my build_android.sh content:

#!/bin/bash
NDK=/home/rango/Desktop/android-ndk-r10e
SYSROOT=$NDK/platforms/android-19/arch-arm/
TOOLCHAIN=$NDK/toolchains/arm-linux-androideabi-4.8/prebuilt/linux-x86

Finally i got it to work . The problem was that it can't find the lib's location. I typed this command : locate libfaac. and from the output i realized that its under "/usr/lib/i386-linux-gnu/" :

/usr/lib/i386-linux-gnu/libfaac.a

/usr/lib/i386-linux-gnu/libfaac.so

/usr/lib/i386-linux-gnu/libfaac.so.0

/usr/lib/i386-linux-gnu/libfaac.so.0.0.0

so what i did next is adding this line to "./build_android.sh" to tell it to look there:

--extra-ldflags=-L/usr/lib/i386-linux-gnu/

so the script becomes:

#!/bin/bash
NDK=/home/rango/Desktop/android-ndk-r10e
SYSROOT=$NDK/platforms/android-19/arch-arm/
TOOLCHAIN=$NDK/toolchains/arm-linux-androideabi-4.8/prebuilt/linux-x86

function build_one
{
