There might be something in your ~/.swank.lisp.  You can also try to
remove ~/.slime/fasl/*.

There is a section "Loading Swank faster" in the manual.  It's not quite
up-to-date but the basics are still the same.  These days you need to
call swank-loader:init.  Also note, that swank-loader:init doesn't
reload Swank if the package already exists, i.e. the same setup can be
used if Swank is the core or not.

To build the core file, load up everything you need, like so:

$ sbcl   # sbcl with a clean core
cl-user> (load "swank-loader.lisp")
cl-user> (swank-loader:init)
;; If you want to include contribs also do the following:
;; cl-user> (mapc #'swank::swank-require swank-loader::*contribs*)
cl-user> (save-lisp-and-die "sbcl.core-with-swank")

For the Emacs side initialization, clbuild seems to set slime-backend to
.../clbuild/.swank-loader.lisp.  This works and it should also work if
Swank isn't in the core.  You could also create a setup like the one in
the manual. E.g.

(setq slime-lisp-implementations 
      '((clbuild (".../clbuild/clbuild" "preloaded")
              :init (lambda (file coding)
                      (format "(swank:start-server %S :coding-system %S)\n" 
                              file (slime-coding-system-cl-name coding))))))
