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.
