Indeed, all these settings are done the same way in the root Makefile of 
the kernel.
Since KBUILD_VERBOSE doesn't seem to be used anywhere else in Buildroot 
(not even in support/kconfig), I also tend to think that this could be 
removed.

What should we do next?
I'm not familiar enough with all these verbose settings, and also with 
the kernel, to be able to check that we're not breaking anything when 
removing them.
Should I first send a patch that moves the export in the right place 
that you have suggested?
Or wait for a cleaning of all these exports?

Regards,
