After talking with x265 development team, adding "-lstdc++" flags should not be the corrective action.  
Instead, configure ffmpeg with --pkg-config-flags=--static option, this issue is solved.
By adding --static, x265.pc gives -lc++ or -lstdc++ with --cflags to ffmpeg.  

In addition, x265.pc’s Libs.private line contains absolute path of libclang_rt.osx.a (Mac) to be linked.  This was minor bug in x265.  I confirmed “-l” is removed today.
