charset="UTF-8" Distributions like Fedora ship a statically compiled binutils libbfd that depends on zstd to decompress sections (e.g. undefined reference to 'ZSTD_decompress'). Since libbfd does not reliably distribute a .pc file for pkg-config, perf probes manual linker flag combinations in fallback chains (-lbfd -ldl -liberty -lz). Extend the testing cascade in tools/perf/Makefile.config to check libbfd-liberty-z-zstd and append '-lbfd -lopcodes -liberty -lz -lzstd' when detected.
