Unfortunately, no. Not without changing the entire architecture of
the kernel build system. The current system depends on each Makefile
maintaining an independent state (think "stack frame") by means of a
lot of local variables. These variables have standard names and
functions, so you can't flatten the recursion without clobbering them.

Yes, we know recursive make is considered harmful - that's why Keith
Owens designed a nonrecursive solution last year. (And quite a nice
piece of work it was, too.) But to achieve his solution he basically
redesigned the whole system from scratch. Pretty much the *only*
thing kbuild2.5 has in common with current kbuild is a minimal set of
functional requirements.
