PATCH move arm to GDB_MULTI_ARCH_PARTIAL

[Richard Earnshaw <rearnsha at arm dot com>]

The ARM targets are now running at GDB_MULTI_ARCH_PARTIAL....

2002-02-08  Richard Earnshaw  <rearnsha@arm.com>

	* arm-tdep.c (arm_frame_chain_valid): Make static.
	(arm_push_arguments): Likewise.
	(arm_gdbarch_init): New function.
	(_initialize_arm_tdep): Call it.
	* config/arm/tm-arm.h (GDB_MULTI_ARCH): Set to 1.
	(TARGET_DOUBLE_FORMAT): Test TARGET_BYTE_ORDER, not target_byte_order.
	(FRAME_CHAIN_VALID): Delete.
	(arm_frame_chain_valid): Delete declaration.
	(PUSH_ARGUMENTS): Delete.
	(arm_push_arguments): Delete declaration.
	(CALL_DUMMY_P): Delete.
