[Buildroot] [RFC PATCH v3 1/2] makedevs: only warn when xattr support disabled

Hi Yann, others,

>   - first, when iputils is enabled, then the build will by default fail,
>     as xattr support is by default disabled,

>   - I can very well see a scenario where xattr, and thus capabilities,

Good point, I've sent v4 with this change.
Thanks for your review!

Regards to xattr support by default disabled, could you please have a look at
other my patch, which set default according to xattr support of used rootfs?

NOTE to reviewers: I've cleaned up previous versions in patchwork (set superseded)

Kind regards,
