Mathias, these flags were added to the xsimd build to avoid accessing
the NEON code path on armhf, which is still an issue

cf. https://github.com/xtensor-stack/xsimd/issues/889
    https://github.com/llvm/llvm-project/issues/30190
    

If -mfpu=vfpv3 is not constructive to use now, can you advise on the
right flag for switching off neon?  Is it
  -cpu neon=off
