You want to test for system-dependent features with Make?  How does
one do that?  All those HAVE_foo macros in the sources -- how do you
compute them with Make?  Wouldn't we end up with heaps of Make
wizardry only a few understand?

IME, the slowest part is byte compilation of Lisp files.  Of course,
that is only a significant factor when you bootstrap or rebuild large
parts of Emacs, but still.
