That doesn't sound right. You should only need to call
(use-foreign-library tcl) only once, some time before you load your
bindings.

Just tested with GNU CLISP 2.41 (2006-10-13) on OSX. Loaded cffi-test,
saved an image (tried with ":executable t" too), restarted with the
image, and ran (rt:do-tests) and it works. (Except some funcall.*
tests fail at first, for some reason. I blame it on some RT
weirdness.)

AFAICT, CLISP correctly reloads the libraries at startup. Can you try
this with cffi-test or otherwise provide some sort of test case?
