Only absolute O= parameters are supported as Makefile.include will always resolve relative paths in relation to $(srctree) instead of the current directory. Add a call to "make outputmakefile" to verify that the sourcetree is clean. This is based on Zhangjins out-of-tree patch. It extends that work for get_init_cpio support and also drops relative O= specifications explicitly.
