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?
