Issue Description:

#1535 made GYB run with python2.7, but #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.

Sounds like the way to fix this is to change the following line in the top-level CMakeLists.txt:

find_package(PythonInterp REQUIRED)


find_package(PythonInterp 2.7 REQUIRED)
if(…) # check if 2.7 wasn't found
  find_package(PythonInterp 3 REQUIRED)

and then test it, because I just wrote that here without trying it myself.
