kbuild: allow to override Python command name
The specification of Python 3 is largely different from that of
Python 2.
For example, arch/ia64/scripts/unwcheck.py seems to be written
in Python 2, not compatible with Python 3.
It is not a good idea to invoke python scripts with the hard-coded
command name 'python'. The command 'python' could possibly be
Python 3 on some systems.
For that case, it is reasonable to allow to override the command name
by giving 'PYTHON=python2' from the command line.
The 'python' in arch/ia64/Makefile should be replaced with '$(PYTHON)'.
