make world == make {clean,kdelete,dist}, I use dist all the time and it
doesn't build any kernels, so unless clean or kdelete are doing it...
Update: I've tried world, it doesn't build kernels for me.

In any case the list of kernels to build is in config/Linux.mk, which I
sure hope isn't being looked at on other platforms.

Even if I try and build the kernels manually:
        $ make kernels
        for i in  ; do make $i-install || exit 1; done
        $

Christoph, what does this command do for you?

Ian.
