Yes
Tested-by: Thomas Ilsche <thomas.ilsche@tu-dresden.de>

Plase note that your patch requires the previous patch that just set the default to python2.

I tested in an Arch Linux VM with:
A) no system install of python, source installation 2.6.9 in PATH
B) no system install of python, source installation 2.7.6 in PATH
C) python3 (as python) and python2 system installation

In all cases it reports to build with libpython and perf script with a dummy Python script
works.

If no python whatsoever is in PATH it reports:

config/Makefile:121: The path 'python' is not executable.
sh: line 0: command: -c: invalid option
command: usage: command [-pVv] command [arg ...]
config/Makefile:122: The path '-config' is not executable.

And the created perf executable does not work with the dummy script.

If only pthon3 is in PATH I get the expected version error message (build stops.)

Note that for the manual old installations of python I had an issue with linking order and
a -Werror issue that I resolved manually. But this is fixed with the latest system install
of python.

Best,
Thomas
