[Libreoffice] make experts: progress information?

Hi LO Make experts,

Is it possible to get subproject build progress information dynamically 
from Make?  Among other things, moving all projects to tail_build 
currently reduces the usefulness of the Zenity SVG clock build progress 
meter.  I'm looking at snippets like

Which is a sexy command line solution for a single Makefile.  What I 
don't know is how well something like this could be implemented for our 
many scattered makefiles.

Beyond myself, are others interested in having a finer-grained 
indication of "where is the build currently in the whole process?"?
