Wrong approach. This messes up kbuild 2.5. The config tools should
not know where the files are being read from or written to, you have
hard coded knowledge about the tree structure into the config system.

kbuild 2.5 handles this by constructing a set of symlinks then invoking
the configure system under those symlinks, followed by copying any
results to their destination. The symlink tree completely isolates
the config system from any knowledge of where its inpuuts and outputs
really are, everything looks local.

You have a 750+ line patch to imbed tree knowledge into configure, that
knowledge will have to be duplicated for any new CML tools. kbuild 2.5
does it in a few lines of scripts/Makefile-2.5 which automatically
works for any new CML code.
