perf bpf: Fix handling of minimal vmlinux.h file when interrupting the build
Ingo reported that he was seeing these when hitting Control+C during a perf tools build: Makefile.perf:1149: *** Missing bpftool input for generating vmlinux.h. Stop. The failure happens when you don't have vmlinux.h or vmlinux with BTF. ifeq ($(VMLINUX_H),) ifeq ($(VMLINUX_BTF),) $(error Missing bpftool input for generating vmlinux.h) endif endif VMLINUX_BTF can be empty if you didn't build a kernel or it doesn't have a BTF section and the current kernel also has no BTF. This is totally ok. But VMLINUX_H should be set to the minimal version in the source tree (unless you overwrite it manually) when you don't pass GEN_VMLINUX_H=1 (which requires VMLINUX_BTF should not be empty). The problem is that it's defined in Makefile.config which is not included for `make clean`.
