[PATCH] Common CPP built-ins for NetBSD

[Jason R Thorpe]

Changes to target configs to use them forthcoming.  Also adds a
missing notice to netbsd.h (missing notice dates back at least
to when Jeff committed the initial version).

Committed to mainline.

	* config/netbsd-aout.h (NETBSD_OS_CPP_BUILTINS_AOUT): Define
	common CPP built-ins for all NetBSD a.out targets.
	* config/netbsd-elf.h (NETBSD_OS_CPP_BUILTINS_ELF): Define
	common CPP built-ins for all NetBSD ELF targets.
	* config/netbsd.h: Add missing notice.
	(NETBSD_OS_CPP_BUILTINS_COMMON): Define common CPP built-ins
	for all NetBSD targets.
	(NETBSD_OS_CPP_BUILTINS_LP64): Define common CPP built-ins
	for all NetBSD targets using an LP64 code model.
	(NETBSD_CPP_SPEC): Define CPP_SPEC parts common to all
	NetBSD targets.
