I'm pretty sure that this would mostly be used in quasi-quoted contexts
outside of the actual build to build #:configure-flags, #:make-flags
and inputs.  However, I can't really say there'd be no use of it inside
builds, even if builds typically don't need to check for conditionals
other than tests?
