Why does the Kconfig say it must be enabled? Its just enabled by
default, please disable it. It's in the "Processor type and features"
menu, and should be visible when the EMBEDDED option is on.
If you take one of the default configs this should work atomatically,
e.g. with make x86-native_defconfig.

Yep, fixed.
