Great approach!  I think people will be pretty happy with this, since
I suspect it will speed up build times.

Now we just have to tackle the other half of the equation :-)

Like Alexandre says, you have to use the GNU make trick here to work
around systems with command line length limitations.  With that change
this patch is ok.

Really, we'd like to find a way to write this code so that it doesn't
depend on GNU make at all, but still works on these limited systems.
Nobody has tried to figure out how to do that yet.  We don't even know
if it is reasonably possible.
