This one is removed by PATCH 5/5.

As they don't provide any additional value over O=, I'd prefer to keep
O=. One of the reason for which Buildroot is too complicated today is
because there are multiple ways of achieving the same thing. This
multitude of options is confusing for newcomers.

See PATCH 5/5, these are completely changed to something else.

Sincerly,
