latest ffmpeg for android

[tewi]

hi, i create a script to parse ffmpeg makefile and generate file list for android makefile.
and i configure the source as following:
./configure \
--enable-hardcoded-tables \
--enable-cross-compile \
--cross-prefix=arm-none-linux-gnueabi- \
--arch=armv6j \
--cpu=arm1136jf-s \
--target-os=linux \
--enable-pic
after configuration, following changes should apply to config.h if android toolchain is not used for generating config.h
1. android cross compiler does not understand "restrict"
2. no log2 and log2f in bionic libm.so
3. soundcard.h is located in linux/soundcard.h
4. no posix_memalign
and then i created a NDK project to work with it, it should work, but...
SharedLibrary  : libffmpeg.so
