FFMPEG for Android toolchains: arm-linux-armeabi-eabi-pkg-config - is there any toolchain in existence containing the pkg-config tool

Does anybody know any toolchain for ffmpeg linux arm platform which contains the arm-linux-androideabi-pkg-config tool? The Android NDK does not contain it. Also has anybody succeeded in building ffmpeg for android that contains the alsa device? Please note that libasound is present on my Ubuntu x86 PC. After very extensive research visiting forums including ffmpeg.org, ffmpeg--nabbles, groups.google.com including the andro and android-ndk gropus, and the Internet in general, I have not succeeded in finding anyone who seems to know of its existence. At best, I have read people saying ignore it. Considering what it is needed for, I consider that a naive thing to say. A careful review of the standard ffmpeg configure script shows that for certain input and output devices a toolchain described as pkg_config_default=pkg-config is required. Also all items on the HAVE_LIST are SYSTEM DEPENDENT. The configure script states very clearly what dependencies are required for each indev or outdev item. Apparently this tool is used then to verify the libraries which are needed for the dependencies This is what happens when you attempt to configure ffmpeg for android jasongipsyblues@android-master:~/android-ffmpeg/Project/jni$ ./configure_ffmpeg.sh ... ... .. ....

On a PC with Ubuntu there is no issue with pkg-config.
