erlc uses the following startup flags: "erl +A0 +sbtu -noinput -mode
minimal -boot start_clean"

So, it uses the smp emulator if available.

If startup time is important, I think the time would be better spent
optimizing the startup time of the smp-emulator, then to maintain the
non-smp emulators just for it's startup speed.
