I am not sure if it is a "good" example (might not use official 
recommended practices) but GraphicsMagick (~300K lines of code) has 
been using non-recursive make since not long after Automake supported 
it.

Parallel build is shown to scale very well on multi-core systems 
(tested on up to 64 cores).  I am observing 86% per-core scalability 
for fully optimized (-O2) debuggable (-g -g3 -ggdb) builds, with the 
linker being the main limiter of scalability.

Make sure to avoid any directory recursion and avoid use of things 
like libtool convenience libraries.

Try to simplify the dependency chain so as many files may be compiled 
at once as possible.
