Generate NULL definition as part of vmlinux.h. This is a pretty common and unfortunate annoyance that most users of vmlinux.h have to deal with. Patch #2 drops such custom NULL definition in one of the selftests. Patches #3 and #4 make bpftool and selftests compilations stricter by treating warnings as errors.
