These changes broke building Emacs in the source tree: now all the
*.eln files produced by the build's ELC+ELN rule are written to the
user's eln-cache directory instead of into native-lisp subdirectory of
the build tree.  To reproduce, touch, say, lisp/files.el or delete
lisp/files.elc, and then say "make" -- you will see that the *.eln
file is written under ~/.emacs.d/eln-cache, and if you also delete the
corresponding files-NNNN.eln file from native-lisp, Emacs will load
files.elc during loadup.
