From: Jiri Olsa <jolsa@xxxxxxxxxx> [ Upstream commit 09d59c2f3465fb01e65a0c96698697b026ea8e79 ] We're missing -lcap in test-all.bin target, so in case it's the only library missing (if more are missing test-all.bin fails anyway), we will falsely claim that we detected it and fail build, like: $ make ... Auto-detecting system features: ... dwarf: [ on ] ... dwarf_getlocations: [ on ] ... glibc: [ on ] ... libbfd: [ on ] ... libbfd-buildid: [ on ] ... libcap: [ on ] ... libelf: [ on ] ... libnuma: [ on ] ... numa_num_possible_cpus: [ on ] ... libperl: [ on ] ... libpython: [ on ] ... libcrypto: [ on ] ... libunwind: [ on ] ... libdw-dwarf-unwind: [ on ] ... zlib: [ on ] ... lzma: [ on ] ... get_cpuid: [ on ] ... bpf: [ on ] ... libaio: [ on ] ... libzstd: [ on ] ... disassembler-four-args: [ on ] ...
