Before this patch libbpf always do feature check even when cleaning.
For example:
$ cd kernel/tools/lib/bpf
$ make
Auto-detecting system features:
... libelf: [ on ]
... bpf: [ on ]
CC libbpf.o
CC bpf.o
LD libbpf-in.o
LINK libbpf.a
LINK libbpf.so
$ make clean
CLEAN libbpf
CLEAN core-gen
$ make clean
Auto-detecting system features:
... libelf: [ on ]
... bpf: [ on ]
CLEAN libbpf
CLEAN core-gen
$
Although the first 'make clean' doesn't show feature check result, it
still does the check. No output because check result is similar to
FEATURE-DUMP.libbpf.
This patch uses same method as perf to turn off feature checking when
'make clean'.
