graphviz: Extend for nativesdk

The "dot" tool is often used together with doxygen which is already
available for nativesdk.

Cross compiling graphviz for nativesdk looks quite similar as building
for target. At installation time of the SDK, "dot -c" must be called in
order to create <SDK sysroot>/usr/lib/graphviz/config6.
