+# overriding the flags included here. But for some, perf does not add
+# any -O option, so ensure the distro's chosen optimization gets used
+# for those. Since ${SELECTED_OPTIMIZATION} always includes
+# ${DEBUG_FLAGS} which in turn includes ${DEBUG_PREFIX_MAP}, this also
+# ensures perf is built with appropriate -f*-prefix-map options,
