This series follows up on the discussion in [1] for fixing the static linkage issue in bpftool. Patch 01 introduces a new feature for libelf-zstd. If this feature is detected, it means the zstd lib is required by libelf. Patch 02 is a minor improvement for linking the zstd lib in the perf. Patch 03 fixes the static build failure by linking the zstd lib when the feature-libelf-zstd is detected.
