Oh, thanks! I didn't want to start actually debugging this before being 
sure I'm not missing some basic thing. Do note however that all of waf 
has been replaced for 4.10, so maybe it's more a matter of getting this 
back in shape than bisecting.

I wanted to push forward another cross-compilation patch that involves 
removal of an explicit path of Heimdal headers, so I wanted to see if 
that breaks system-heimdal build and then realized it's broken before 
the patch.

Uri.
