'make' is a rather poorly designed language, IMHO, for all sorts of
reasons. (Can't blame the designers -- that was a long time ago, and
they didn't know any better.)
But recursive make is a big efficiency problem. It's not so terrible on
Linux, but on Cygwin, it's a disaster (because windows process creation
is slow). I once sped up a build that was taking well over 10 hours
down to 1 hour by removing recursive make. The speedup on Linux was
less dramatic. That was a project with about a million lines of Ada
code. I don't remember the hardware.
Here's a paper that explains why "Recursive Make Considered Harmful":

And here's a fun recursive essay about "Considered Harmful":

OK, you win. ;-) DOS batch files are worse than 'make' files.
