Not sure I understand. probe-file.h explicitly calls out a need for 
libelf due to the probe cache and related routines - commit 
40218daea1db1 ("perf list: Show SDT and pre-cached events").

However, if you prefer to retain the ftrace README scanning here, we can 
drop this patch and I can update patch 6 to check for libelf.

Thanks,
