This patch in the series removing svr4.h from the headers used by
particular targets in GCC stops cris*-*-linux* from using svr4.h,
defining the two macros used from that header in cris/linux.h instead.

Tested building cc1 and xgcc for a cross to cris-linux-gnu.  OK to
commit?

	* config/cris/linux.h (SIZE_TYPE, PTRDIFF_TYPE): Define.
	* config.gcc (crisv32-*-linux* | cris-*-linux*): Don't use svr4.h.
