In a full test, all test cases are built twice with tools/perf/Makefile and tools/perf/Makefile.perf. 'Makefile' automatically computes parallel options for make, but 'Makefile.perf' not, so all test cases is built with one job. It is very slow. This patch adds '-j' options to Makefile.perf testing. It computes parallel building options like what tools/perf/Makefile does, and pass '-j' option to Makefile.perf test.
