I think we should check this in cmake too. TestCases/Posix/asan-symbolize-sanity-test.cc fails if I run the tests using a python 2.6 install with this error:

Traceback (most recent call last):
  File "/path/to/llvm/projects/compiler-rt/lib/asan/scripts/asan_symbolize.py", line 10, in <module>
    import argparse
ImportError: No module named argparse

, but works fine with a 2.7 build, so enforcing 2.7 at configure time seems like a good idea.
