    build: libgfxdr.so calls GF_FREE(), needs to link with -lglusterfs

    The previous change to remove the xdrgen script exposed (or
    created) a recursive build dependency: libglusterfs needs the
    generated headers, and libgfxdr should be linked with libglusterfs
    for GF_FREE/__gf_free.

    (Much grumbling about libglusterfs being the kitchen sink of gluster
    elided. This would not be necessary if there were two or more libs,
    a gluster "runtime" library with common gluster code shared by the
    xlators and daemons, and a utility library with things like the
    rbtree, memory allocation, and whatnot.)

    So. Link at build time or link at runtime? For truth-and-beauty, link
    with libglusterfs.so at build time. Without truth-and-beauty, don't
    link with libglusterfs and rely on the other things that link with
    libglusterfs to provide resolution of __gf_free().

    Truth-and-beauty it is. But how to generate the headers first, then
    build libglusterfs, then come back and build libgfxdr? Autotools is a
    maze of twisty passages, all different. Things that work with gnu
    make on linux don't work with the BSD make. Finally I hit on this
    solution. Add a shadow directory where make only generates the headers,
    then build libglusterfs using the generated headers, and finally build
    libgfxdr and link with libglusterfs.
