Ok, you could try running directly from tools/bpf/bpftool/ next time
instead.

Readline at least is for a different tool under tools/bpf/, bpf_dbg (But
I'm still not sure where that ncurses requirement was pulled from). The
requirements for specific kernel options probably came from yet another
tool (runqslower, I think).
