Python in ./configure

[Greg Toombs]

Firstly, it seems that your www build has a dependency on Python 2.7,
but ./configure allows selection of Python 3.x, which it should not.

Secondly, ./configure does not correctly determine the presence of
C:\Python27. It instead fails the 2.x test and takes 3.x instead.

My current workaround requires running configure like:
PYTHON=/c/Python27/python ./configure
