bug#57001: make: No such file or directory after `rm loaddefs-gen.elc`

[Stefan Kangas]

When I do this to force a recompile of loaddefs-gen.elc:

    rm lisp/emacs-lisp/loaddefs-gen.elc; make -j8

I get the following:

Error: file-missing ("Cannot open load file" "No such file or
directory" "./emacs-lisp/loaddefs-gen.elc")

I guess it's fixed by this, but it'd be better to byte-compile it:
