perf tools: Add 'build-test' make target Currently various build test can be performed using a Makefile named tests/make, so one needs to remember and specify it with -f option on command line. Add the 'build-test' target in the main Makefile as a shortcut.

perf tools: Allow shuffling the build tests Those tests take a long time and sometimes we stop it, so allow randomly shuffling the tests so that we have a better chance of running more of them in partial 'make build-test' runs. Using it just on the 'build-test' target, i.e.: make -C tools/perf build-test Is equivalent to: make SHUF=1 -C tools/perf -f tests/make Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: David Ahern <dsahern@gmail.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Wang Nan <wangnan0@huawei.com> Link: http://lkml.kernel.org/n/tip-ey7461i9q4k8u0987j8guun6@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

perf build: Fix single target build dependency check Currently if we build a single target like: $ touch util/map.c && make util/map.o It will not rebuild util/map.o if it already exists and util/map.c is modified. The reason is that the top-level 'Makefile' processes util/map.o as an implicit rule and if util/map.o exists make considers the 'util/map.o' target as done and will not nest into Makefile.perf. Adding FORCE for '%', because that's what we want to nest into Makefile.perf for any target. Adding Makefile into phony targets, because make tries to rebuild it and it's also resolved as '%' target.

perf tools: Fix tags/TAGS targets rebuilding Once the tags/TAGS file is generated it's never rebuilt until it's removed by hand. The reason is that the Makefile does not treat tags/TAGS as targets but as files and thus won't rebuilt them once they are in place. Adding PHONY tags/TAGS targets into Makefile.
