Oooooh, right, terrible.

What about adding (srfi srfi-1) to ‘%default-modules’ in (guix
build-system gnu)?  It’s generally useful anyway.

(Alternately, we could rename SRFI-1’s ‘delete’ in (guix build utils),
so we’d still be matching a literal, but we’d have problems in places
that use both (guix build utils) and (srfi srfi-1).)
