The scenario above works now, but when I attempt to actually use the value
it reappears:

(eval-when (:compile-toplevel :load-toplevel :execute)
  (defparameter foo (lambda ())))

(funcall (load-time-value foo))

deepfire at canopus:~/local$ ecl -eval '(compile-file "foo.lisp")'
;;; Loading #P"/usr/lib/ecl/cmp.fas"
;;; Loading #P"/usr/lib/ecl/sysfun.lsp"
;;; Compiling foo.lisp.
;;; Compiling (DEFPARAMETER FOO ...).
An error occurred during initialization:
Object #<bytecompiled-function 0838cbb8> cannot be externalized.
