Log:
    PR debug/49032
    * dbxout.c: Include cgraph.h.
    (dbxout_expand_expr): If a VAR_DECL is TREE_STATIC, not written
    and without value expr, return NULL if no varpool node exists for
    it or if it is not needed.
    * Makefile.in (dbxout.o): Depend on $(CGRAPH_H).

    * gcc.dg/debug/pr49032.c: New test.
