[PATCH] NetBSD signal trampoline fixes

[Jason R Thorpe <thorpej at wasabisystems dot com>]

NetBSD recently switched to signal trampolines which are provided by
libc, not the kernel.  This patch updates most of the NetBSD targets
to reflect that (changes for the ones not addressed by this patch are
forthcoming -- some touch shared-by-other-targets code).

Committed to trunk.

	* Makefile.in (mipsnbsd-tdep.o): Add nbsd-tdep.h to dependency
	list.
	(nbsd-tdep.o): Add $(gdb_string_h) to dependency list.
	* alphanbsd-tdep.c (alphanbsd_pc_in_sigtramp): Use
	nbsd_pc_in_sigtramp.
	* mipsnbsd-tdep.c: Include nbsd-tdep.h.
	(mipsnbsd_pc_in_sigtramp): Use nbsd_pc_in_sigtramp.
	* nbsd-tdep.c: Include gdb_string.h.
	(nbsd_pc_in_sigtramp): New function.
	* nbsd-tdep.h (nbsd_pc_in_sigtramp): New prototype.
	* ppcnbsd-tdep.c (ppcnbsd_pc_in_sigtramp): New function.
	(ppcnbsd_init_abi): Set gdbarch_pc_in_sigtramp to
	ppcnbsd_pc_in_sigtramp.
	* shnbsd-tdep.c (shnbsd_pc_in_sigtramp): New function.
	(shnbsd_init_abi): Set gdbarch_pc_in_sigtramp to
	shnbsd_pc_in_sigtramp.
	* sparcnbsd-tdep.c (sparcnbsd_init_abi_elf): Set
	gdbarch_pc_in_sigtramp to nbsd_pc_in_sigtramp.
	* config/mips/nbsd.mt (TDEPFILES): Add nbsd-tdep.o.
