This is a fuller set of patches from v1 addressing build problems
linking with libbfd when zstd is a dependency. The original issue was
exposed on Fedora with perf's build-test. This series separates the
build from the perf changes and adds in bpftool and objtool fixes
caught by Sashiko. The changes follow the pattern used by the zlib -lz
dependency and so appear correct but are untested.
