Specifically, to determine whether a binary needs to be grafted, Guix
must check whether that binary depends on one of the things that we
would graft.
To do that, it must either have access to substitute information, or
have a local build of the thing at hand.
Thus, when substitutes are lacking, it will tend to build things right
away so that it can answer that question.
I agree this isn’t great, but I’m not sure how to improve on that.
(Nevertheless, it is better than answering the question based on
compile-time dependencies as was done before.)
