The generic extension set 'G' is realy a base with the minimal set of extensions needed to be comfortable (but not required) to run a linux-bassed system. Similarly, we consider the custom to be about the custom set of features (not about a custom core implementing such a set). As such, we allow that a core with the G set can have futher extensions without requiring it to be configured as a custom set. We drop the intermediate symbols with the prompts, and move the prompts to the previously hidden symbols, and add a prompt for the I set. This alows one to clearly see what the generic set is about, without having to delve into the help and hunt the list of selected symbol. Note however that the G set implies Zicsr and Zifencei, but we have no prompt for thos two, because in Buildroot, we assume that they are mandatory and always present, like the I set (which they previously were part of).
