Add config_enabled() from Linux

This change is taken from Linux. It allows to check for Kconfig
definitions in the preprocessor and source code using the same
idiom.

Long term plan is to remove our Kconfig hack to #define values to 0,
and this helps.

This includes a tiny modification to the macros to fix romcc support.
