Yes, you are right. I was assuming that each defconfig file must
define CONFIG_TARGET_ in order to tie itself to corresponding
include/configs/*.h header. It turns out it's not true and I obviously
need to check ".config" file for CONFIG_TARGET_* definition after
doing "make ..._defconfig". This is because some defconfig files
doesn't have CONFIG_TARGET_ definition, but it's enabled as
dependency, or as default value, or whatever. Also I think it's good
idea to check modified defconfig files for consistency with "make
savedefconfig" rule.

I'm going to revise this patch and will submit new version soon.
