llvm failed to build on 10.9.1

I'm getting a configure error when building with or without --without-python:

checking for python >= 2.5...   File "<string>", line 1
    import
         ^
SyntaxError: invalid syntax
./configure: line 12394: test: : integer expression expected
not found
configure: error: found python  (/usr/local/Library/ENV/4.3/python); required >= 2.5
See `config.log' for more details.

The error doesn't occur when built with --universal (probably because of env :std). I'm guessing this is linked to #26140.

This appears to have been fixed.
