>From: Robert Schwebel <r.schwebel@pengutronix.de>
>Subject: add python path for cross compiling
>
>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.
