[RFC/RFA]Fix cross build of m68k netbsd target

[Pierre Muller]

tm-nbsd.h in config/m68k directory
contains 
#include ""
and
#include sys/param.h"

This is totally wrong and should be refused in all cases,
as it totally prevents correct cross-compilation
to that target.

I thus propose the following patch,
which  enables me to cross-compile
with target m68k-uunknown-netbsd.

A simple grep show wthat this problem is not unique:
$ grep -n -i "#include *<" config/tm*.h config/*/tm*.h
config/i386/tm-fbsd.h:27:#include <sys/param.h>
config/i386/tm-i386aix.h:28:// OBSOLETE #include <sys/reg.h>
config/i386/tm-ptx.h:30:#include <sys/reg.h>
config/i386/tm-symmetry.h:32:#include <machine/reg.h>
config/m68k/tm-dpx2.h:34:#include <sys/types.h>
config/mips/tm-mips.h:38:#include <bfd.h>

These should probably also be fixed....

	* config/m68k/tm-nbsd.h:
	(sys/param.h, machine/vmparam.h): Remove wrong includes.
	(PGSHIFT, HIGHPAGES,NBPG, USRSTACK): New macros,
	taken from a native m68k netbsd machine.
