BULLS EYE!

Thanks very much for your assistance.

I have been able to build with libx264 for android 4.4 with the following
configure line:

./configure --arch=arm --target-os=linux  --enable-cross-compile \
--cross-prefix=/4.4/prebuilts/gcc/linux-x86/arm/arm-linux-androideabi-4.7/bin/arm-linux-androideabi-
\
--sysroot=/4.4/prebuilts/ndk/current/platforms/android-18/arch-arm \
--enable-gpl --enable-avresample --enable-libx264 \
--extra-cflags='-fno-builtin-sin -fno-builtin-sinf' \
--extra-ldflags='-L/4.4/external/x264'
