	* ChangeLog: Correct date on last entry.
	* arm-linux-tdep.c (arm_linux_push_arguments): New function.
	* config/arm/tm-linux: Redefined PUSH_ARGUMENTS for Linux.
	* config/arm/tm-embed: Fix build warning from redefinition of
	LOWEST_PC.
	* config/arm/tm-arm.h: Remove TARGET_BYTE_ORDER_SELECTABLE.
	* config/arm/tm-wince.h: Remove TARGET_BYTE_ORDER_SELECTABLE and
	TARGET_BYTE_ORDER.  Add TARGET_BYTE_ORDER_SELECTABLE_P to
	override default in tm-arm.h.  Use default target byte order
	from tm-arm.h.
