svr4.h avoidance: frv

svr4.h avoidance: frv

[Joseph S. Myers]

This patch in the series removing svr4.h from the headers used by
particular targets in GCC stops frv-*-elf and frv-*-*linux* (which
covers all frv-* targets) from using svr4.h, defining the macros used
from that header in frv.h instead.

Tested building cc1 and xgcc for crosses to frv-elf and frv-linux-gnu.
OK to commit?

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