I see, I rarely messed up externally the repo and always used make to
build.

I suspect this is due to some confusion or a different issue to the
discussed one.

AFAIU if a file is compiled by `batch-byte-native-compile-for-bootstrap'
the elc can be produced only after the eln.

I think so, but playing with the build system can be time consuming,
especially to obtain a portable solutions.  Given that when we'll have
dynamic scope compilation will be sufficient just not to produce the
.elc I decided not to invest more time on this.

If you want to suggest a patch to have the eln files as target this is
very welcome.  Consider that the other complication is the eln folder
with the hash that should be know to the build system, so probably a two
step solution is required.

Thanks
