			The various build lines from libtraceevent and perf mix up during a
parallel build and produce unaligned output like:
    CC builtin-buildid-list.o
    CC builtin-buildid-cache.o
    CC builtin-list.o
  CC FPIC            trace-seq.o
    CC builtin-record.o
  CC FPIC            parse-filter.o
    CC builtin-report.o
    CC builtin-stat.o
  CC FPIC            parse-utils.o
  CC FPIC            kbuffer-parse.o
    CC builtin-timechart.o
    CC builtin-top.o
    CC builtin-script.o
  BUILD STATIC LIB   libtraceevent.a
    CC builtin-probe.o
    CC builtin-kmem.o
    CC builtin-lock.o
To solve this, harmonize all the build message alignments to be similar
to the kernel's kbuild output: prefixed by two spaces and 11-char wide.
After the patch the output looks pretty tidy, even if output lines get
mixed up:
  CC      builtin-annotate.o
  FLAGS:  * new build flags or cross compiler
  CC      builtin-bench.o
  AR      liblk.a
  CC      bench/sched-messaging.o
  CC FPIC event-parse.o
  CC      bench/sched-pipe.o
  CC FPIC trace-seq.o
  CC      bench/mem-memcpy.o
  CC      bench/mem-memset.o
  CC FPIC parse-filter.o
  CC      builtin-diff.o
  CC      builtin-evlist.o
  CC      builtin-help.o
