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

  corresponding command line options, in particular for fat builds (i.e.,
  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.
