When there is a missing input file (vmlinux.o or Module.symvers), you are likely to get a ton of unresolved symbols. Currently, Kbuild automatically adds the -w option to allow module builds to continue with warnings instead of errors. This may not be what the user expects because it is generally more useful to catch all possible issues at build time instead of at run time. Let's not do what the user did not ask. If you still want to build modules anyway, you can proceed by explicitly setting KBUILD_MODPOST_WARN=1. Since you may miss a real issue, you need to be aware of what you are doing. Suggested-by:
