  What I've done in other neon assembly files is to add a

  some files with neon assembly, used at runtime only after some check of
  available instructions), where one might not want the C compiler to emit
  any neon instructions.
If we add support for fat arm builds, then that's what we'll need to do!

I don't know if it could cause some portability problems to add it.
