Kamal Mostafa 4abc2dbd88 selftests/bpf: Clarify build error if no vmlinux ... commit 1a3449c19407a28f7019a887cdf0d6ba2444751a upstream. If Makefile cannot find any of the vmlinux's in its VMLINUX_BTF_PATHS list, it tries to run btftool incorrectly, with VMLINUX_BTF unset: bpftool btf dump file $(VMLINUX_BTF) format c Such that the keyword 'format' is misinterpreted as the path to vmlinux. The resulting build error message is fairly cryptic: GEN vmlinux.h Error: failed to load BTF from format: No such file or directory This patch makes the failure reason clearer by yielding this instead: Makefile:...: *** Cannot find a vmlinux for VMLINUX_BTF at any of "{paths}". Stop.
