re PR target/10190 ([IRIX] building gcc 3.2.2 on irix 5.3 fails)

	* config/mips/iris5.h (TARGET_OS_CPP_BUILTINS): Define _LONGLONG.
	Define _ABIO32.
	Use it for _MIPS_SIM.
	* config/mips/iris6-o32.h (TARGET_OS_CPP_BUILTINS): Removed.

	* config/mips/iris6-o32-as.h (SUBTARGET_ASM_OPTIMIZING_SPEC):
	Moved ...
	* config/mips/iris5.h (SUBTARGET_ASM_OPTIMIZING_SPEC): ... here,
	updating comment.
	Fixes PR target/10190.
