So there must be some different regression then, as this is readily
reproducible for me on v6.9, as per the build log below - I simply
Ctrl-C-ed a build, and the next build results in:
kepler:~/tip/tools/perf> make clean install
Makefile.perf:1149: *** Missing bpftool input for generating vmlinux.h. Stop.
make: *** [Makefile:90: clean] Error 2

Thanks,

This happens easily on latest upstream v6.10-rc1 as well:

What's going on here?
