perf feature detection: Add -lopcodes to feature-libbfd
Both libbfd and libopcodes are distributed with binutil-dev/devel. When libbfd is present, it is OK to assume that libopcodes also present. This has been a safe assumption for bpftool. This patch adds -lopcodes to perf/Makefile.config. libopcodes will be used in the next commit for BPF annotation.
