Because the .el files are pre-compiled in a normal Emacs release, make
clean does not (and should not) delete .elc files. If you want to patch
lisp files, I advise you to use a more thorough `make maintainer-clean'
first. This is unnecessary for the vast majority of people building a
release. (I haven't actually tested your example.)
