Yes I think too `native-elisp-load' and `dump_do_dump_relocation' are
the two places we'd want to trigger the rebase (not sure if in
`dump_do_dump_relocation' we are already able to spawn subprocesses
tho).
That said I'm wondering what is going to happen if an Emacs is running
and a second sessions starts rebasing some eln.
