Thanks for this.  I have narrowed down the problem.

Under emacs 26.1, commands like this are failing.

/usr/local/bin/emacs-26.1 --batch --no-init-file --no-site-file -L . \
--eval '(setq byte-compile-dest-file-function (lambda (_) "bbdb.elc"))' \
-f batch-byte-compile 'bbdb.el'

If I change it to

/usr/local/bin/emacs-26.1 --batch --no-init-file --no-site-file -L . \
--eval '(setq byte-compile-dest-file-function (lambda (_) 
"/full/path/of/pwd/bbdb.elc"))' \
-f batch-byte-compile 'bbdb.el'

or

/usr/local/bin/emacs-26.1 --batch --no-init-file --no-site-file -L . \
-f batch-byte-compile 'bbdb.el'

there are no errors.

The problem is isolated to our package building tool, poudriere.  To get
(more) reproducible builds, it uses things like nullfs mounts and clean
jails.  Something about this setup is triggering a problem in 26.1 that
appears to have been fixed in the master branch.

In any case, I have patched the Makefile to remove the

--eval '(setq byte-compile-dest-file-function (lambda (_) "bbdb.elc"))' \

and the package is building again.  Unless anyone has a less ad-hoc
solution, I will commit this change to get the packages out again.
