qemu-native: Point python to python2 on build host

On buildhosts where default python has switched to using python3 qemu-native fails configure like this

| ERROR: Cannot use 'python', Python 2.6 or later is required.
|        Note that Python 3 or later is not yet supported.
|        Use --python=/path/to/python to specify a supported Python.
|

we still expect build host to have python2 pre-installed and is always available.

2.11.1

What distro is this that ships python as python3?

Ross

Arch for instance:

maciek@corsair:~ ls -l /usr/bin/python
lrwxrwxrwx 1 root root 7 01-16 12:14 /usr/bin/python -> python3

Pretty sure that it's only Arch here as everyone else listens to Python instead of thinking they know best...

(reads PEP-394 and sighs)
