Sure, we can do it via a command-line argument instead.  Perhaps this
fits well with the proposed --native-compile-sync switch, even.

That is, instead of that, we could have a --native-compile-mode command
line switch with the values --native-compile-mode=none,
--native-compile-mode=sync and --native-compile-mode=normal?

Or a better name for the switch, if anybody has an idea -- I don't much
like "mode" here, since that can be confused with Emacs modes...
