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.
