I have the same issue.

The bug is that the configure script contains code snippet to check the
Python version, but this snippet does not work for Python 3 and up.

The code is in llvm-3.3.src/autoconf/configure.ac, line 1330-1341:

The print statement is invalid in Python 3; it should be a print
function. but it is probably easier to simply use python -V, instead of
this small script.

I would recommend to change the ac_python_version assignment to:

ac_python_version=`$PYTHON -V 2>&1 | cut -d ' ' -f2`
