If you can do that that binary will be able to calculate also disk space used, 
it could be something very cool, allowing to remove not only progress_bar.sh 
but also all that du and time calls. 

It it also can improve the build performance due that no other external 
programs or sub-shells need ve invoked, that idea is a winner.

The issues that I can think on in this momment is about how that program will 
be invoked. The console output drawing should start when make start running a 
target. Disk usage need be meassured before unpacking a package and before 
deleting the package sources build tree. And SBU is calculated for the actual 
build and installation time. That meant three different hocks points.
