[PATCH RFC 01/17] kconfig: allow setting CONFIG_ from the outside

[Ahmad Fatoum]

Regular config options apply build-wide. Security config options will
be enabled depending on the policy that's currently active.

To allow using an SCONFIG_ prefix for the latter, introduce
KCONFIG_CONFIG_ to affect this.
