kbuild: Introduced build-targets

build-targets is used to list targets that is always built.
This allowed misuse of EXTRA_TARGETS to be deleted.
built-in.o is now only created for directories defining a obj-* variable,
avoiding this for scripts and lxdialog

One Makefile needed a dummy obj- statement
