stat_map_32 and stat_map_64.
(cb_libgloss_stat_map_32): New stat map.
(stat_map_32, stat_map_64): New stat map pointers.
(bfin_user_init): Assign stat_map_32 to cb_linux_stat_map_32 and
stat_map_64 to cb_linux_stat_map_64.
(bfin_virtual_init): New function.
(sim_create_inferior): Call bfin_virtual_init for all other envs.
