In Makefile.perf, ALL_PROGRAMS includes SCRIPTS (perf-archive, perf-iostat). However, unlike PROGRAMS and DLFILTERS, SCRIPTS was not prefixed with $(OUTPUT). During out-of-tree builds (or when O= is specified), Make checked for the unprefixed target 'tools/perf/perf-archive'. Since the actual script was installed into $(OUTPUT)perf-archive, Make concluded the target was missing and continuously re-executed the script installation rule on every single incremental build. Prefix SCRIPTS with $(OUTPUT) and update the static pattern rule to ensure Kbuild correctly tracks generated script prerequisites during incremental builds.
