The problem is that you need one rule

    bytecomp.elc: bytecomp.el
        ELC ...

to build the byte-compiled compiler, and then another rule:

    bytecomp.elc: bytecomp.el bytecomp.elc comp.elc macroexp.elc cconv.elc ...
        ELC+ELN ...

to build the native compiled compiler using the byte-compiled compiler
(which is much faster than the interpreted compiler).

In an ideal world the second rule would not have `bytecomp.elc` as its
target but would have something like `bytecomp.eln` instead, but we have
not yet been able to teach Make how to compute the name of the generated
`.eln` file (it's not just `bytecomp.eln` but includes some hash of the
Emacs binary).
