There was a breaking change to binutils objdump that causes partial instructions to no longer be dumped. This behavior is different from what the "Object code reading" test expects. Add a Kconfig variable that checks the version of objdump and conditionally enables the perf test fix for riscv objdump versions effected by this issue. A binutils patch has been sent as well to fix this in objdump [1].
