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.
