no rule to make target ../lib/libz.a needed for target
../images/zImage.prep (and simulair for openfirmware...), or something
like that (I have to this from what I remember) I found a file
../lib/lib.a, so I assumed it was renamed, not updating the makefile for
the prep and openfirmware image

This is a linking error in the final stage of the build.... I think
2.5.33 als build ok, after a few patches. Booted as far a to tell me
there was an attempt to kill pid 0 and the do its 180 sec. countdown...
