Oh I see.  It’s a problem that ‘tunable?’ in itself doesn’t solve.

The fix would be twofold: (1) remove ‘-march’ and similar compiler
arguments that cause it to generate code that assumes AVX availability,
and (2) add the ‘tune?’ property for those who want a fine-tuned binary.

Could you look into it?

Thanks,
Ludo’.
