This commit introduces a "copy-builtin" script designed to prepare a kernel source tree for building ZFS as a builtin module. The script makes a full copy of all needed files, thus making the kernel source tree fully independent of the zfs source package. To achieve that, some compilation flags (-include, -I) have been moved to module/Makefile. This Makefile is only used when compiling external modules; when compiling builtin modules, a Kbuild file generated by the configure-builtin script is used instead. This makes sure Makefiles inside the kernel source tree does not contain references to the zfs source package. Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Issue #851
