Commit 6283f55ea1 updated _almost_
everything to use the correct top level object directory. This
was done to correctly supporting building in custom directories.
Unfortunately, I missed this one instance in the zfs-module.spec.in
rpm spec file. Fix it.
Add autoconf style build infrastructure to the ZFS tree. This
includes autogen.sh, configure.ac, m4 macros, some scripts/*,
and makefiles for all the core ZFS components.
