Stanislav Fomichev 14541b1e7e perf build: Don't unconditionally link the libbfd feature test to -liberty and -lz ... Current libbfd feature test unconditionally links against -liberty and -lz. While it's required on some systems (e.g. opensuse), it's completely unnecessary on the others, where only -lbdf is sufficient (debian). This patch streamlines (and renames) the following feature checks: feature-libbfd - only link against -lbfd (debian), see commit 2cf9040714 ("perf tools: Fix bfd dependency libraries detection") feature-libbfd-liberty - link against -lbfd and -liberty feature-libbfd-liberty-z - link against -lbfd, -liberty and -lz (opensuse), see commit 280e7c48c3 ("perf tools: fix BFD detection on opensuse") (feature-liberty{,-z} were renamed to feature-libbfd-liberty{,z} for clarity) The main motivation is to fix this feature test for bpftool which is currently broken on debian (libbfd feature shows OFF, but we still unconditionally link against -lbfd and it works). Tested on debian with only -lbfd installed (without -liberty); I'd appreciate if somebody on the other systems can test this new detection method.
