[PATCH] KConfig: Rewrite globals only if modified

[Chusslove Illich]

As it is now, KConfig will issue rewrite of global config whenever component
config is dirty, regardless if global config is dirty itself. This may be a
problem for caching global config data, e.g. as that done by kstartupconfig.

The attached patch checks if there is any dirty global config entry, and
issues rewrite only if that is the case. Is it committable?
