PATCH: configure error when cross compiling dbus core 0.94

[Marco Pracucci]

Hi,

I had a problem when I tried to cross compile (arm) dbus core sources. Configure script exits with error:
checking abstract socket namespace... configure: error: cannot run test program while cross compiling

I've written a simple patch that adds an "abstract socket namespace" entry to config.cache, so you can set this option editing config.cache file, when cross compiling. The patch is attached below.

NOTE: a similar patch should be applied to dbus-glib binding sources.
