When building kernel objects with the O= option, scripts/Makefile.lib automatically adds both -I$(srctree)/$(src) and -I$(obj) so each Makefile does not need to add them explicitly. In contrast, scripts/Makefile.host adds only -I$(obj) when building host programs with the O= option. As a result, each Makefile must add the extra option to include checkin headers from generated C files. Let's cater to this in the build system for consistency, and drop extra options from the kconfig, dtc, genksyms Makefiles.
