> This commit adds a number of hidden Config.in options, that will be
> used to handle dependencies on the gcc version. We mimic the model
> that was used for the kernel headers dependency mechanism.

> These hidden options will be selected by the internal and external
> toolchain backend logic respectively, in follow-up commits.
