I'm using this script to do all the heavy lifting:

   https://github.com/kewlbear/FFmpeg-iOS-build-script

Here are the four configure lines and I think the problem is in the i386 library. I am beginning to think I should define my arch as x86_32 which would cause ffmpeg's configure script to supply this linker flag for darwin builds:

   enabled x86_32 && append SHFLAGS -Wl,-read_only_relocs,suppress
