See my reply to your e-mail.

I don't understand what you mean here. We have options in Buildroot to
allow the user to configure whether (s)he wants a soft float or hard

As I said in my other e-mail, what you should investigate is precisely
why the config_hardfloat test is returning the wrong result.

Best regards,

Thomas
