Commit ed63f34c026e9a60d17fa750ecdfe3f600d49393 ("perf tools: Make perf
depend on libbpf") dynamically creates FEATURE-DUMP.libbpf during the
perf building, but the .gitignore under tools/lib/bpf/ mistakes
FEATURE-DUMP.libbpf for FEATURE-DUMP. Besides, the Makefile under
tools/lib/bpf/ also mistakes FEATURE-DUMP.libbpf for FEATURE-DUMP, which
causes that "make clean" will leave (or say create) FEATURE-DUMP.libbpf
rather than remove FEATURE-DUMP.libbpf file.

Ok, so the cset that created files with a .libbpf suffix was this one:
commit 65f041bee783
Author: Arnaldo Carvalho de Melo <acme@redhat.com>
Date: Mon Sep 21 17:25:27 2015 -0300
tools lib bpf: Use FEATURE_USER to allow building in the same dir as perf
-------
That has this tag:
Fixes: 1b76c13e4b36 ("bpf tools: Introduce 'bpf' library and add bpf feature check")
---
The cset you mention, ed63f34c026e9a60d17fa750ecdfe3f600d49393, just
makes perf call the code introduced by 1b76c13e4b36 and fixed by
65f041bee783, i.e. you start noticing, when building perf, that those
files are created.
Anyway, fixing it up, thanks for the patch!

Yes, right. Thanks for your detailed explanation.

tools lib bpf: Change FEATURE-DUMP to FEATURE-DUMP.libbpf
Commit ed63f34c026e9a60d17fa750ecdfe3f600d49393 ("perf tools: Make perf
depend on libbpf") triggers the build of libbpf when building the perf
tools, dynamically creating FEATURE-DUMP.libbpf.
It failed to update the tools/lib/bpf/.gitignore file to have that
prefix, fix it.
