Ah, *that* is the point of rebuilding the Makefile every time. Sounds
like you are tried to write a better make utility, not better Makefiles.
Just curious: If kbuild does all the work usually done by make (i.e.
check timestamps, look what needs rebuilding, ...), why do you need make
at all? IMHO this is bad designed: People know what make is and how it
works, but kbuild (ab)uses make in different ways. Which is bad from
the usability point of view because people simply don't expect that.
That is the reason why the question about the Makefile generation comes
up again and again. And I'm pretty sure that will never stop if you
keep that design.
I think you should either use make the usual way, i.e. let make do all
the timestamp checking (I know it is less strict, but I don't think it
is a big issue because developers know how make works and what the
pitfalls are). Or don't use make at all.
