Good idea, build is running, but is sluggish just from the first sight. 
Running already for 1h20m and still building stage1. This is more in 
line with 8.0.1 I'm afraid. Anyway, I'll update with proper time once it 
is at the end.

Looks like I'll also need to do 7.8.x build to see where we are on this...
