Not really convenient :(
AFAICS, VERBOSE is not an official env. var. altering Buildroot's
behavior, unlike V [1].

If VERBOSE should only be set for cmake-based package, in addition to
globally unexport it, I'd prefer:
- either fix the cmake infra to keep the same behavior from the user
point of view;
- or update the doc.

I prefer the 1st option.

I think it is intentional (given [2] and the number of occurences of
"\<VERBOSE\>" in the cmake code base ;-]).
