I see thanks.

I think the way to do it is to proceed as we do in the current Emacs
build that is; express to make only the .elc targets and produce them
using `batch-byte-native-compile-for-bootstrap'.

This is like `batch-byte-native-compile' but produces also the .elc
files.

At this point if packages wants to use this function we should probably
rename it as is not anymore in use only for our build process.

Does this make sense?

Thanks
