Python 2.6 does not have subprocess.check_output:

$ ./scripts/checkkconfig.py
INFO: processing Kconfig files...
INFO: checking kconfig parameter 1 / 13706 (0 %)
Traceback (most recent call last):
  File "./scripts/checkkconfig.py", line 127, in <module>

  File "./scripts/checkkconfig.py", line 67, in count_param
    count = subprocess.check_output('git grep ' + param + '| grep -v
defconfig | wc -l', shell=True)
AttributeError: 'module' object has no attribute 'check_output'
