Good idea! I rebased your work over recent changes and adopted it a bit,
see below. Hope you still like it. :)

I'm no makefile guru, but from all I read this is true. So I included
that cleanup as well.

---------->
Derived from Stuart Brady's patch: Show the target directory as prefix
to the current module when building in quiet mode. This helps to gain
overview of the current build progress, specifically when running
parallelized builds.
Furthermore, suppress make command echoing when entering subdirs and
replace $(subst subdir-,,$@) with $* in the related rule.
