first now you have possibly different x264 stuff lying around
that is why i decided for /usr/local/x264 to not collide with
system packages

second you should post "ls -a" outputs instead of descriptions

below my x264 and ffmpeg configure (you need to translate the rpm macros)
AFAIK it's important to disable most stuff for a static x264 useable
to link with ffmpeg - in case of non x86_64 maybe you need to reduce
the linker flags by trial and error

./configure \
 --host=x86_64-redhat-linux \
 --prefix=%{_prefix}/local \
 --exec-prefix=%{_prefix}/local \
 --bindir=%{_prefix}/local/bin \
 --libdir=%{_prefix}/local/lib64 \
 --includedir=%{_prefix}/local/include \
 --extra-cflags="-O3 -std=c99 -fomit-frame-pointer -fno-strict-aliasing" \
 --extra-ldflags="-Wl,-z,now -Wl,-z,relro,-z,noexecstack" \
 --enable-static \
 --disable-avs \
 --disable-cli \
 --disable-ffms \
 --disable-gpac \
 --disable-lavf \
 --disable-opencl \
 --disable-swscale

./configure \
 --prefix=%{_prefix}/local \
 --bindir=%{_prefix}/local/bin \
 --datadir=%{_prefix}/local/share/ffmpeg \
 --incdir=%{_prefix}/local/include/ffmpeg \
 --libdir=%{_prefix}/local/lib64 \
 --shlibdir=%{_prefix}/local/lib64 \
 --mandir=%{_prefix}/local/man \
 --arch=x86_64 \
 --cpu=corei7 \
 --extra-cflags="-I%{_prefix}/local/x264 -O3 -fomit-frame-pointer -fno-strict-aliasing" \
 --extra-ldflags="-I%{_prefix}/local/x264 -L%{_prefix}/local/x264 -ldl -Wl,-z,now -Wl,-z,relro,-z,noexecstack" \
