the directories at the top level but that proved troublesome. The kernel buildsystem and autoconf were conflicting too much. To resolve the issue I moved the kernel bits in to a modules directory which can then only use the kernel build system. We just pass along the likely make targets to the kernel build system. git-svn-id: https://outreach.scidac.gov/svn/spl/trunk@11 7e1ea52c-4ff2-0310-8f11-9dd32ca42a1c
