Do not compile backgraph.c unless configure '--enable-gc-debug'

* Makefile.am (libgc_la_SOURCES): Exclude "backgraph" entry from
unconditional list; add this entry only if MAKE_BACK_GRAPH.
* configure.ac (MAKE_BACK_GRAPH): New AM conditional (defined only if
enable_gc_debug explicitly set to yes).
