If you talk about ~/.emacs.d/elpa, it won't, because there is a separate
package-user-dir variable for that.
The problem can arise if we have emacs installed in a few profiles, I'm
not sure if it is a good idea to do so, but it is possible, in such a case
we will have a few items in the package-directory-list. A fix for that:
(setq package-directory-list
(mapcar (apply-partially 'string-remove-suffix "/elpa")
package-directory-list)))

It's true, but it seems relatively easy to implement a build phase,
which will generate -pgk.el in case it is missing.
