Well, I can't say I like it - we have the config item
CONFIG_DEFAULT_MESSAGE_LOGLEVEL and DEFAULT_MESSAGE_LOGLEVEL resembles
it for a reason - it is the corresponding define coming from .config.

With this change you have:

CONFIG_DEFAULT_MESSAGE_LOGLEVEL
       MESSAGE_LOGLEVEL_DEFAULT

which is more confusing. To me at least. I can't see the resemblance at
a quick glance anymore.
