tools/perf/build: Automatically build in parallel, based on number of CPUs in the system
Implement automatic parallel builds when building in tools/perf:
$ time make
# [ perf build: Doing 'make -j12' parallel build. ]
Auto-detecting system features:
...
real 0m9.265s
user 0m59.888s
sys 0m6.082s
On GNU make achieving this is not particularly easy, it requires a separate
makefile, which then invokes the main Makefile.
( Note: this patch adds Makefile.parallel to show the concept - the two
makefiles will be flipped in the next patch to avoid having to specify -f
to get parallelism in the default build. )
