Subject: [PATCH 36/44] perf feature detection: Add -lopcodes to feature-libbfd
From: Song Liu <songliubraving@...com>
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.
