[x264-devel] does not link lavf support

[Yasuhiro Ikeda]

1. Uninstall swscale and other libraries in /usr/lib64.
2. Compile and install libav. `./configure --prefix=$HOME/local --enable-gpl
--disable-debug && make && make install` is enough, don't add any other
options.
3. Compile x264. `./configure --enable-static
--extra-cflags=-I$HOME/local/include --extra-ldflags=-L$HOME/local/lib &&
make` is enough, don't add any other options.
4. Delete $HOME/local if you want. `rm -rf $HOME/local`
5. Run x264 binary. `./x264 test.avi -o test.264` is enough, don't add any
other options.
6. Report again.
