This introduces a duplicate field initializer in the expanded 'package'
object, because the 'dummy-package' macro introduces its own
'build-system' field initializer.  From (guix tests):

  (define-syntax-rule (dummy-package name* extra-fields ...)
    "Return a \"dummy\" package called NAME*, with all its compulsory fields
  initialized with default values, and with EXTRA-FIELDS set as specified."
    (package extra-fields ...
             (name name*) (version "0") (source #f)
             (build-system gnu-build-system)
             (synopsis #f) (description #f)
             (home-page #f) (license #f)))

If you need to use trivial-build-system, then I think you can't use the
'dummy-package' macro as it's currently implemented.
