You can do it from outside if you use N instanceses of Emacs leveraging
`batch-native-compile'.

Another option would be to run one Emacs leveraging
`native-compile-async', but you'll have to add some simple custom code
to have Emacs wainting for all compilation to be finished before
exiting.  `native-comp-async-all-done-hook' might be of hand there.
