    media-libs/libaom: workaround bugs in intrinsic-enabled/disabled builds
    
    - For 32-bit multilib builds on amd64, force on SSE3 & SSSE3. It seems
      to check at runtime anyway (for some targets, inc. this one).
    
    - For arm32-on-arm64 builds, go generic, because it gets confused by ARM64
      when NEON is disabled (I think?). Could try forcing arm at some point.
