* Makefile.in (i386nbsd-tdep.o): Add $(arch_utils_h),

Browse source 
$(i386_tdep_h), and nbsd-tdep.h to dependency list.
* i386-tdep.h (i386bsd_init_abi): New prototype.
* i386bsd-tdep.c (i386bsd_init_abi): Remove "static" from
function declaration.
(_initialize_i386bsd_tdep): Don't register OS ABI handlers
for NetBSD-a.out or NetBSD-ELF.
(i386nbsd_sigtramp_start, i386nbsd_sigtramp_end)
(i386nbsd_sc_pc_offset, i386nbsd_sc_sp_offset)
(i386nbsd_init_abi, i386nbsdelf_init_abi): Move to...
* i386nbsd-tdep.c: ...here.  Include arch-utils.h, i386-tdep.h,
and nbsd-tdep.h.
(i386nbsd_pc_in_sigtramp): New function.
(i386nbsd_init_abi): Set gdbarch_pc_in_sigtramp to
i386nbsd_pc_in_sigtramp.
(_initialize_i386nbsd_tdep): Register i386nbsd_init_abi
and i386nbsdelf_init_abi OS ABI handlers.
* config/i386/nbsdaout.mt (TDEPFILES): Add nbsd-tdep.o.
