    I don't understand why it would be slower. Maybe I'm clueless but I thought
    you were moving more towards a single makefile system, kind of like what
    BSD had about 15 years ago, you went to /sys/MYMACHINE and typed make and
    it did the build completely in that directory. You did different configs
    by running a configure tool that made /sys/MYMACHINE /sys/YOURMACHINE, etc.

    If this is the general approach, shouldn't this be a lot faster than the
    current approach? The current approach stats stuff many times. Linux is
    really good at making stats cheap, but nothing is as good as not doing it
    twice.

    Am I completely misunderstanding what kbuild is all about? My apologies
    if so...
