The goal is to avoid generating a non-buildable kernel in the first place. This is very usefull for automatic check harness that run randconfig, for example (but may have more use-cases). > I.e., those steps: > 1. make <whatever>config > 2. make => A prereq. target runs the shell script. This is too late, since this will bail out, and will give a false-positive failure. While if we were to check for _known_ needed tools before calling into Kconfig, we can simply hide non-available config options, and even inform the user *why* the option is not available.
