    C++: Initialize a couple const globals
    
    In C++ mode, we get:
    
     src/gdb/gdbserver/tdesc.c:43:33: error: uninitialized const â??default_descriptionâ?? [-fpermissive]
      static const struct target_desc default_description;
    				  ^
     In file included from src/gdb/gdbserver/tdesc.c:19:0:
     src/gdb/gdbserver/tdesc.h:26:8: note: â??const struct target_descâ?? has no user-provided default constructor
      struct target_desc
    	 ^
