System.  The builder is run with GUILE, or with the distro's final Guile
package if GUILE is #f or omitted.

The builder is run in a context where MODULES are used; IMPORTED-MODULES
specifies modules not provided by Guile itself that must be imported in
the builder's environment, from the host.  Note that we distinguish
between both, because for Guile's own modules like (ice-9 foo), we want
to use GUILE's own version of it, rather than import the user's one,
which could lead to gratuitous input divergence.

SUBSTITUTABLE? determines whether users may be able to use substitutes of the
returned derivations, or whether they should always build it locally.

ALLOWED-REFERENCES can be either #f, or a list of packages that the outputs
are allowed to refer to.  Likewise for DISALLOWED-REFERENCES, which lists
packages that must not be referenced."
