Ingo Molnar 3fae82db55 perf tools: Align perf version output to other build messages
Before:

  CC util/pmu.o
  CC util/parse-events.o
PERF_VERSION = 3.12.rc4.g1b30c
  CC util/parse-events-flex.o
  GEN perf-archive

After:

  CC util/pmu.o
  CC util/parse-events.o
  PERF_VERSION = 3.12.rc4.g1b30c
  CC util/parse-events-flex.o
  GEN perf-archive
