I diffed the profiles.go you sent against the known-good profiles.go
that I have.  There’s a lot of noise in the diff (different addresses,
etc.), but the interesting bit is this (the minus signs correspond to
the “bad” .go file):

It confirms that the bad code creates a <gexp> structure with the empty
list as its ‘modules’ field instead of '((guix build utils)).

That’s clearly a Guile bug.
