Shouldn't there be problems with unquoted 'dependency-dirs' list? IIUC
the following:
(emacs-byte-compile-directory "/tmp/foo" '("one" "two"))
will produce the following elisp expression:
(progn
(add-to-list (quote load-path) "/tmp/foo")
(unless (null ("one" "two"))
(setq load-path (append load-path ("one" "two"))))
(byte-recompile-directory (file-name-as-directory "/tmp/foo") 0))
but that will raise an error ‘(invalid-function "one")’. Or did I miss
anything?
Also I believe dependency-dirs should have a preference over other
'load-path' directories.
So what about the following variant:

(define* (emacs-byte-compile-directory dir #:optional (dependency-dirs '()))
"Byte compile all files in DIR and its sub-directories. Before compiling
the files, add DIR and all directories in DEPENDENCY-DIRS to 'load-path'."
(let ((expr `(progn
(add-to-list 'load-path ,dir)
(when ',dependency-dirs
(setq load-path (append ',dependency-dirs load-path)))
(byte-recompile-directory (file-name-as-directory ,dir) 0))))
(emacs-batch-eval expr)))
