Sorry, I missed the patch.

Please use the KBUILD_OUTPUT variable and not O. Also, the $tree prefix
should only match at the beginning of the filename (so use something
like ${i#$tree}). Last, but not least, the .[cS] -> .o substitution only
needs to be done once. The k variable can use the value of j instead of i.

Thanks,
Michal
