commit: https://git.buildroot.net/buildroot/commit/?id=c68ec4297ec9fea58fab910fe095bbfefd11c6f8
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

The non-SMP scheduler was deprecated with the Erlang/OTP 20.0 release and
slated for removal with the next major Erlang release. Since the non-SMP
scheduler isn't even built anymore, this option no longer has the
intended effect of saving space or compile time. The SMP scheduler
supports both SMP and non-SMP processors, so removing the option will
not break any platforms.

We do not need to add a legacy entry, because the new behavior is the
same as with the option previously set (i.e. SMP enabled).
