This patch in the series removing svr4.h from the headers used by
particular targets in GCC stops mn10300-*-* from using that header.

The macros used from that header are added to mn10300.h.  Because
am33_2.0-*-linux* does not use svr4.h and so got the default
definitions of these macros, they are then undefined in
mn10300/linux.h to preserve this.

Tested building cc1 and xgcc for crosses to mn10300-elf and
am33_2.0-linux-gnu.  (The latter build fails with "targhooks.c:342:
undefined reference to `print_operand_address'", a pre-existing
problem probably caused by r165778.)  OK to commit?

	* config/mn10300/linux.h (SIZE_TYPE, PTRDIFF_TYPE, WCHAR_TYPE,
	WCHAR_TYPE_SIZE): Undefine.
	* config/mn10300/mn10300.h (SIZE_TYPE, PTRDIFF_TYPE, WCHAR_TYPE,
	WCHAR_TYPE_SIZE): Define.
	* config.gcc (mn10300-*-*): Don't use svr4.h.

OK.
