Commita808a2b35f("tools build: Fix fixdep dependencies") broke the perf build ("make -C tools/perf") by introducing two inadvertent conflicts: 1) tools/build/Makefile includes tools/build/Makefile.include, which defines a phony 'fixdep' target. This conflicts with the $(FIXDEP) file target in tools/build/Makefile when OUTPUT is empty, causing make to report duplicate recipes for the same target. 2) The FIXDEP variable in tools/build/Makefile conflicts with the previously existing one in tools/perf/Makefile.perf. Remove the unnecessary include of tools/build/Makefile.include from tools/build/Makefile, and rename the FIXDEP variable in tools/perf/Makefile.perf to FIXDEP_BUILT.
