Issue Description:

https://github.com/apple/swift/pull/1535 made GYB run with python2.7, but https://github.com/apple/swift/pull/6463 effectively reverted the change because GYB is run with PYTHON_EXECUTABLE instead of using shebang line. This causes the problem 1535 fixed to reappear.

研究方向
Investigate the CMake configuration files in the repository that invoke GYB. Look at the referenced PRs #1535 and #6463 to understand the previous fix and its reversal. The issue is that GYB is run using PYTHON EXECUTABLE instead of explicitly using python2.7. Modify the CMake to ensure python2.7 is used. Check for any other occurrences where the Python version might be ambiguous.
