7333	python2	michalt		"Currently GHC assumes that the ```python``` command defaults to Python 2.x, but on
some systems (e.g., Arch Linux) it's already Python 3.x.  This breaks the
testsuite completely.  According to http://www.python.org/dev/peps/pep-0394/ on
*nix systems one should prefer ```python2``` command.  I'm not very familiar with the
build system of GHC but my quick solution is to:

 - make configure.ac check for python2
 - make the testsuite also try python2 first
 - remove the shebang line from ```calibrate``` (testsuite/timeout) since make already calls it with the value
   of ```PYTHON``` variable
 - change the shebang in ```timeout.py``` (in testsuite/timeout) to use python2, which
   should be safe on Unix like systems (and on Windows we don't actually use timeout.py)

Btw is the ```PythonCmd``` (defined by configure.ac) actually used somewhere -- I can't
seem to find where..."	bug	closed	normal		Build System	7.6.1	fixed			Unknown/Multiple	Unknown/Multiple	None/Unknown	Unknown
