patch to add --with-python-includes for cross compilation

When cross compiling dbus-python, we need to build a python for the
"build" machine and one for the "host" system. The current test for
python headers incorrectly grabs up the "build" headers, although this
package is built for the "host" machine.

This patch adds a "--with-python-includes=<path>" switch, which makes it
possible to overwrite the autodetected path with a pre-known one. Thus
it is possible for cross build systems like ptxdist, buildroot etc. to
set an already known path while cross compiling.

For the sake of a concrete example, suppose you have Python 2.6 in --prefix=/opt/misc and want to use that (hence you need something like "-I/opt/misc/include/python2.6" in your CPPFLAGS).

It seems your patch results in this usage:

    ./configure --with-python-includes=/opt/misc/include

which I find surprising - I'd have expected to have to include the Python-version-specific part as well.

I've applied a patch which instead results in this usage:

    ./configure PYTHON_INCLUDES="-I/opt/misc/include/python2.6"

which is consistent with how you'd override PYTHON, DBUS_CFLAGS and so on.

Since you reported this bug I'd added a use of PYTHON_LIBS, so I've allowed that to be overridden in the same way.

Fixed in git for 0.84.0.
