[PATCH 2/2] distutils: clean the build tree in do_configure

[Ross Burton <ross.burton@intel.com>]

base_do_configure() tries to do "make clean" if there is a Makefile present.
For most recipes using distutils there is not a Makefile, but we do know that
"setup.py clean" will work so call that instead.
