Fail to configure without an LLVM-friendly Python
This addresses issue #2720. According to LLVM's documentation, it requires a version of Python between 2.4 and 2.7. Without the proper version, LLVM fails to build with cryptic errors. Prior to this commit, the configure script checked for the `python` command in the environment, but didn't actually check the version, which can cause problems e.g. on Linux distros where the default is Python 3. Now the configure script always prefers to select a more specific version of Python when available, in the order `python2.7` > `python2.6` > `python2` > `python`, and will always check to ensure that the interpreter's version is in the correct range.
