It happens today, but it depends on architecture.  An allyesconfig on
ia32 should have it set and possibly a few others.  There's no reason an
x86-64 couldn't have it set, it's just that x86-64 was the architecture
break where ISA was discontinued, so there's no real point building that
configuration.
