In principle I'd say so, otherwhise we'll keep accumulating filenames in
`comp--delayed-sources' for all the session.

If we don't want to have errors raised by the deferred compilation when
an Emacs with native comp support is running without the native compiler
available I think we should guard against `native-comp-available-p'
inside 'maybe_defer_native_compilation'.  WDYT?

Thanks
