Afaik, scons rebuilds if dependencies change or if the command line used
to generate a target changes (that's why changing defines causes
rebuilds). I know there isn't a big push to write bb v2 on top of scons
atm, but I think it would be as close to an awesome build system as you
can get. Especially if python is made a first-class citizen of the
jamfile.

Personally, I'm hacking around with a lisp based build system on my free
time (not much of that) using what I've learnt from bjam and scons. It
kind of sucks but it probably tracks dependencies correctly!

It feels like the perfect build system is just within reach, if it
weren't for the annoying imperfections :( Maybe a couple of more years.
