BUG: linux-2.6.0-test6: make -O=/var/tmp/build help

Hello

Maybe i´m not up-to-date, but i tried out the new 2.6 kernel with the new -O option and it fails with:
Without the -O option it works. Normally one calls make help and not make -O.. help, but this fails also, if the environment variable for -O is set.

[Append $(srctree)/ to path to makefiles.
