fix march sanity check issue

1. check if gcc_test is really generate before os.remove("gcc_test") to avoid
   following error:
      ERROR: Execution of event handler 'check_sanity_eventhandler' failed
      Traceback (most recent call last):
      File "check_sanity_eventhandler(e)", line 4, in check_sanity_eventhandler(e=<bb.event.ConfigParsed object at 0x3151450>)
      File "sanity.bbclass", line 107, in check_sanity(sanity_data=<bb.data_smart.DataSmart object at 0x11ba110>)
      File "sanity.bbclass", line 22, in check_gcc_march(sanity_data=<bb.data_smart.DataSmart object at 0x11ba110>)
      OSError: [Errno 2] No such file or directory: 'gcc_test'
2. set result to False when build failed with -march=native to ensure
   -march=native is appended to BUILD_CFLAGS  when host gcc really supports this flag,
   otherwise following error appears when build native packages.
      | cap_text.c:1: error: bad value (native) for -march= switch
      | cap_text.c:1: error: bad value (native) for -mtune= switch
