kbuild: modpost: read modules.order instead of $(MODVERDIR)/*.mod
Towards the goal of removing MODVERDIR, read out modules.order to get
the list of modules to be processed. This is simpler than parsing *.mod
files in $(MODVERDIR).
For external modules, $(KBUILD_EXTMOD)/modules.order should be read.
I removed the single target %.ko from the top Makefile. To make sure
modpost works correctly, vmlinux and the other modules must be built.
You cannot build a particular .ko file alone.
