Unconditionally enable debugging for libzpool We already enable -DDEBUG unconditionally (meaning regardless of this is a debug build or a performance build) for zdb and ztest as they are mostly used for development and debugging. This patch enables -DDEBUG for libzpool extending the debugging checks for zdb, ztest, and a couple of other test utilities. In addition to passing -DDEBUG we also enable -DZFS_DEBUG so all assertion checks work s expected. We do so not only in libzpool but in every utility that links to it, even if the utility doesn't directly use any functionality wrapped in ZFS_DEBUG macro definitions. The reason is that these utilities may still include headers that contain structs that have more fields when ZFS_DEBUG is defined. This can be a problem as enabling that flag for libzpool but not for zdb can lead into random problems (e.g. segmentation faults) as zdb may be have an incorrect view of a struct passed to it by libzpool.

Support parallel build trees (VPATH builds) Build products from an out of tree build should be written relative to the build directory. Sources should be referred to by their locations in the source directory. This is accomplished by adding the 'src' and 'obj' variables for the module Makefile.am, using relative paths to reference source files, and by setting VPATH when source files are not co-located with the Makefile. This enables the following: $ mkdir build $ cd build $ ../configure \ --with-spl=$HOME/src/git/spl/ \ --with-spl-obj=$HOME/src/git/spl/build $ make -s This change also has the advantage of resolving the following warning which is generated by modern versions of automake.

Use abs_top_builddir when referencing libraries libtool stores absolute paths in the dependency_libs component of the .la files. If the Makefile for a dependent library refers to the libraries by relative path, some libraries end up duplicated on the link command line. As an example, libzfs specifies libzfs_core, libnvpair and libuutil as dependencies to be linked in. The .la file for libzfs_core also specifies libnvpair, but using an absolute path, with the result that libnvpair is present twice in the linker command line for producing libzfs. While the only thing this causes is to slightly slow down the linking, we can avoid it by using absolute paths everywhere, including for convenience libraries just for consistency.
